Known But Unresolved Bugs: * In multidrop mode without an applicable localdomain, addresses of the form "foo"@bar.com are not parsed correctly, even though they are technically RFC822 legal. The general problem is mentioned on the man page. Features To Consider * Generate bounce messages when delivery is refused. See RFC1891, RFC1894. * More log levels? * Use the libmd functions for md5 under Free BSD? (Low priority.) * Send notification mail on messages skipped due to --limit? Other TO-DO items: * Get with Craig Metz to write a draft RFC on RFC1938 support in IMAP. Release Notes: ------------------------------------------------------------------------------ fetchmail-4.0.7 (Tue Aug 5 22:47:11 EDT 1997) * Fixed a minor bug in handling of DNS errors in multidrop mode. * Added a `postconnect' analogous to `preconnect'. * Make `interval' count polls skipped because of interface or monitor option. * Fixed UIDL and dropstatus option processing.

Interim release, mainly because I inadvertently messed up the web page. Note: RFC1938 support is tentative, untested, and requires a patch to the LIBOPIE library. See the file LIBOPIE.PATCH for the sad details. There are 258 people on the fetchmail-friends list. fetchmail-4.0.2 (Mon Jul 17 20:54:30 EDT 1997) * Experimental RFC1938 one-time password support using OPIE library, courtesy of Craig Metz (couthor of RFC1938).

This has been fixed. * Compilation fixes for Kerberos V4 support and GNU glibc2 support.

This should eliminate some alarming but harmless "(message incomplete)" messages from the error-logging machinery. * A

		    GNU GENERAL PUBLIC LICENSE
		       Version 2, June 1991

 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
                          675 Mass Ave, Cambridge, MA 02139, USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

			    Preamble

  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.)  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

  To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

  We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

  Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

  Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

  The precise terms and conditions for copying, distribution and
modification follow.

		    GNU GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language.  (Hereinafter, translation is included without limitation in
the term "modification".)  Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

  1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

  2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

    a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.

    b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

    c) If the modified program normally reads commands interactively
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an
    announcement including an appropriate copyright notice and a
    notice that there is no warranty (or else, saying that you provide
    a warranty) and that users may redistribute the program under
    these conditions, and telling the user how to view a copy of this
    License.  (Exception: if the Program itself is interactive but
    does not normally print such an announcement, your work based on
    the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

  3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

    a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections
    1 and 2 above on a medium customarily used for software interchange; or,

    b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above on a medium
    customarily used for software interchange; or,

    c) Accompany it with the information you received as to the offer
    to distribute corresponding source code.  (This alternative is
    allowed only for noncommercial distribution and only if you
    received the program in object code or executable form with such
    an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable.  However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

  4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

  5. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

  6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

  7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

  8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded.  In such case, this License incorporates
the limitation as if written in the body of this License.

  9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

  10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

			    NO WARRANTY

  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.

  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
-------------------------------------------------------------------------------
work around bison's "feature" of silently ignoring 0-value tokens (caused options nokeep, norewrite, nofetchall, noskip to be no-ops). ------------------------------------------------------------------------------ fetchmail-1.3 (Tue Oct 1 05:49:49 1996): * Significant man page improvements. * Escapes for newlines in .fetchmailrc are now optional. * Kill off -2 and -3 options, redundant popclient remnants. * IMAP code simplification and robustification. Use FETCH FLAGS to find seen messages. Code should now work even if unseen messages are interspersed with seen ones, and even if messages are appended to the mailbox during the run. ------------------------------------------------------------------------------ fetchmail-1.2 (Sat Sep 28 15:40:50 EDT 1996): * The great option massacre. Remove --stdout, --limit, --local, --mda. We get a significant code and complexity shrinkage this way (a lot of the configuration machinery goes away too). These things are your MDA's job. (This also kills off the lose-mail-on-disk-full bug, which I've never seen but two users reported.) * Link APOP support by default. * Fix embarrassing Makefile bug. ------------------------------------------------------------------------------ fetchmail-1.1 (Sat Sep 28 09:21:10 EDT 1996): * In POP3, don't send LAST if STAT shows count of waiting messages to be zero. * Document APOP better, we know it works now. * Lose the .fetchids file and give up on POP3 UIDs, they're a dead loss. ------------------------------------------------------------------------------ fetchmail-1.0 (Thu Sep 26 11:59:38 EDT 1996): * SMTP forwarding and header-rewrite features work with POP2 now. * Stricter RFC822 conformance, so SMTP to qmail works. Thanks to Cameron MacPherson for these changes. * The program is quieter but more informative now (suppress printing of server greeting message; add the server host being queried to the message count information line). * Add `skip' option to make it easier to set up test entries. * Name change (it ain't just for POP any more). ============================================================================== popclient-3.2 (Mon Sep 23 13:29:46 EDT 1996): * RPOP support (coded at a user's request but untested). * Ported to QNX (see the Makefile). * Add code by Michael Schwendt <3schwend@informatik.uni-hamburg.de> for improved sizeticker. * Improved RFC822 parsing (thanks to Rob Funk). * Move the per-user lockfile to /tmp so it gets cleared at reboot time. * Warn users that running concurrent instances of popclient is a bad idea. * Try USER and HOME to set defaults before going to the password file. This should work better in Sun NIS environments. popclient-3.1 (Thu Sep 12 15:45:25 EDT 1996): * MDA arguments are now dumped when using the -V option. * Sendmail delivery from background seems to work now. * We have IMAP2bis/IMAP4 support. * Code now autoprobes for a POP3, IMAP, or POP2 server if no protocol is specified. * SMTP forwarding support. Thanks to Harry Hochheiser for this simple but clever idea. It's now the default delivery mode. * If no UNIX From line is found, popclient will now synthesize a correct line from the RFC822 From line. * It is now possible to specify the host TCP/IP port number to connect to. popclient-3.05 (Thu Aug 22 22:59:04 EDT 1996): * Experimental support for RFC1725-compliant POP servers with the UIDL command and without LAST. popclient-3.04 (Wed Aug 21 00:22:44 EDT 1996): * Logfile option works. popclient-3.03: * Minor bug fixes for password querying and redirection to stdout. popclient-3.02 (Fri Jul 19 11:37:56 EDT 1996): * Correct buggy processing of nokeep/noflush/fetchall. * Fix buggy -mda option processing. * Added -N/--norewrite option. * Delivery via sendmail now works in non-daemon mode. popclient-3.01 (Mon Jul 1 13:33:51 EDT 1996): * Fixed a lexical analyzer bug in quoted-string processing. * Fixed a bug in dump_options that caused username to be displayed incorrectly. * The lock assertion code was in the wrong place relative to the daemonize() call. popclient-3.0 (Fri Jun 28 11:33:34 EDT 1996): Eric S. Raymond hacked extensively on 3.0b6 and took over the package with the consent of Carl Harris, the original implementor. Some of the 3.0 feature additions were inspired by Sean Oh's fetchpop 1.8 code, and a few use code directly lifted from fetchpop. Here are my (Eric's) change notes: CONFIGURATION AND BUILDING * The autoconfigure script incorrectly assumed that all Linuxes use /usr/bin/deliver. Under Linux it now checks for both /usr/bin/delivermail and /bin/mail. * I added a distribution-maker production to Makefile.in. OPTIONS AND COMMAND LINE * I have removed the -p command-line option. Given that there's a run control facility there is no excuse for encouraging users to put plaintext passwords in scripts which might be readable. * Calling popclient with no arguments now causes it to query or operate on every host in the run control file. * I have made --version more useful by having it dump the computed connection options for each server specified. * The user can now explicitly set an MDA (such as procmail) with the new option -m or -mda. Various possible MDAs are listed on the man page. POPRC FILE SYNTAX * The run control file lexer now supports "-enclosed strings which may contain whitespace. * I added a --yydebug option to enable run control parser debugging at runtime if the parser was generated with --debug. It's not documented. * You may now have a `defaults' entry in the run control file which sets overrideable values for other entries. See the man page for details. * It is now possible to set keep, flush and fetchall in your run control file. * Fixed incorrect numbering of source lines in run control file parse error messages. * The configure.in specification no longer uses the obsolete AC_TRY_COMPILE macro (it uses AC_TRY_LINK instead). MAILBOX LOCKING * I have added mandatory locking of mailbox files where supported. This will cover Linux systems, in particular. * The default behavior is now to do lock-protected append on the user's system mailbox rather than using delivermail or some other MDA. (This is a performance hack.) * The autoconfigure script now looks for standard mail locations. The default mail delivery agent is used only if it can't find a mail spool directory in the standard places. FUNCTIONAL ENHANCEMENTS * When using POP3, message headers are edited so that replies won't foo up. Anything that looks like a mail ID local to the POP host gets @ and the pop servername attached to it before being appended to the user's mailbox or passed to an MDA. * I have implemented daemon mode. * I have added a lock check to ensure that there is only one popclient running per user, and a --quit option to kill the currently running one. DOCUMENTATION * All changes and feature additions have been tested in actual use and are documented on the man page. * I have turned the comments in the sample run control file into a new manual section documenting the file format. MISCELLANEOUS BUG FIXES * I fixed some de-initialization bugs in pop2.c and pop3.c that led to fd leaks (these became painfully obvious when I tested daemon mode!). * I've fixed the flaky parser error messages. They turned out to be due to a misdeclaration of yytext. These are Carl Harris's change notes from previous releases: 3.0b5 o "From " header fix in pop2.c and pop3.c o Surpress "..." output when --stdout option specified in pop3.c 3.0b4 o alloca fix. o various diagnostic/informational message fixes. 3.0b3 o Support for retrieving only new messages from maildrop when using POP3. o Support for retrieving only the first n lines of each message when using POP3. o APOP authentication support. o Buffered socket input. 3.0b2 This is a "new features" release. o support for .poprc file. o GNU-style long options. o fixed passwords appearing in 'ps' output o support for multiple servers on one command line 3.0b1 This is mostly a test of the autoconfigure integration. Among the functions performed by the new configure script, is the ability to detect known system types, configures the mail delivery agent (MDA) correctly. This should permanently solve the problem of using something other than an MDA for mail delivery (which continues to plague Linux slackware 1.2.9). For this beta, please check the values of MDA_PATH and MDA_ARGS carefully. They should match the values found in your sendmail.cf file on the line which begins with "Mlocal". Other changes from popclient version 2.21: o no longer uses getpass() from the C library. The internal getpassword() function allows the use of long passwords. o integrated GNU getopt() for long options. Long option names will appear in a future beta. o Several compiler warnings fixed. o Fixed problems related to missing include files in Solaris port.
