This is mainly to support * RFC1725-conformant POP3 servers without a LAST command, but may also be * useful for making the IMAP4 querying logic UID-oriented, if a future * revision of IMAP forces me to. * * These functions are also used by the rest of the code to maintain * string lists. * * Here's the theory: * * At start of a query, we have a (possibly empty) list of UIDs to be * considered seen in `oldsaved'. These are messages that were left in * the mailbox and *not deleted* on previous queries (we don't need to * remember the UIDs of deleted messages because ... well, they're gone!) * This list is initially set up by initialize_saved_list() from the * .fetchids file. * * Early in the query, during the execution of the protocol-specific * getrange code, the driver expects that the host's `newsaved' member * will be filled with a list of UIDs and message numbers representing * the mailbox state. If this list is empty, the server did * not respond to the request for a UID listing. * * Each time a message is fetched, we can check its UID against the * `oldsaved' list to see if it is old. * * Each time a message-id is seen, we mark it with MARK_SEEN. * * Each time a message is deleted, we mark its id UID_DELETED in the * `newsaved' member. When we want to assert that an expunge has been * done on the server, we call expunge_uid() to register that all * deleted messages are gone by marking them UID_EXPUNGED. * * At the end of the query, the `newsaved' member becomes the * `oldsaved' list. The old `oldsaved' list is freed. * * At the end of the fetchmail run, seen and non-EXPUNGED members of all * current `oldsaved' lists are flushed out to the .fetchids file to * be picked up by the next run. If there are no un-expunged * messages, the file is deleted. * * Note: some comparisons (those used for DNS address lists) are caseblind! */ /* UIDs associated with un-queried hosts */ static struct idlist *scratchlist; #ifdef POP3_ENABLE void initialize_saved_lists(struct query *hostlist, const char *idfile) /* read file of saved IDs and attach to each host */ { struct stat statbuf; FILE *tmpfp; struct query *ctl; /* make sure lists are initially empty */ for (ctl = hostlist; ctl; ctl = ctl->next) ctl->skipped = ctl->oldsaved = ctl->newsaved = (struct idlist *)NULL; errno = 0; /* * Croak if the uidl directory does not exist. * This probably means an NFS mount failed and we can't * see a uidl file that ought to be there. * Question: is this a portable check?

# Quick hack for fetchmail to locally spool messages.
#
# To spool:
#     fetchmail --mda "fetchspool -t %T %F"
# To de-spool
#     fetchspool -f

# William Boughton comments:
# Still has some potential problems, with using inline from address.
# The use of _ is bad because fetchmails uses this if it notices
# shell escapes.

# Changed to using 3 _@@s to delimit the message, i hope this is ok.
# Whilst i have tested and used this script, with my demon account and
# SDPS, it may still have serious problems, that i've not noticed etc.
