<h1>Fetchmail's Test List</h1>

<p>Here are the server types on my regression-test list:</p>

<table border=1 width=80% align=center summary="Server list">
<tr>
<td><strong>Protocol &amp; Version:</strong></td>
<td><strong>Special Options:</strong></td>
</tr>
<tr><td>IMAP: CommuniGate IMAP server</td><td>IMAPrev1 STARTTLS AUTH=CRAM-MD5 AUTH=DIGEST-MD5</td>
<tr><td>POP3: CommuniGate POP3 server</td><td>CAPA LAST APOP CRAM-MD5</td>
<tr><td>POP3: IntraStore POP3 mail server</td><td>!CAPA LAST</td>
<tr><td>APOP: IntraStore POP3 mail server</td><td>!CAPA LAST APOP</td>
<tr><td>IMAP: IntraStore IMAP mail server</td><td>IMAPrev1 IDLE AUTH=CRAM-MD5 AUTH=SKEY AUTH=ANONYMOUS</td>
<tr><td>POP3: Eudora EIMS</td><td>CAPA LAST APOP SASL CRAM-MD5 NTLM</td>
<tr><td>POP3: gmx.de pop server</td><td>!CAPA UIDL</td>
<tr><td>IMAP: IMail IMAP server</td><td>IMAP4rev1 AUTH=CRAM-MD5</td>
<tr><td>IMAP: Microsoft Exchange</td><td>IDLE AUTH=NTLM</td>
<tr><td>POP3: qpopper 3.1.2 (Eudora) patched with mysql</td><td>CAPA UIDL</td>
<tr><td>IMAP: Courier IMAP</td><td>IMAP4rev1</td>
<tr><td>POP3: Courier POP3</td><td>CAPA UIDL</td>
<tr><td>APOP: Qpopper using APOP</td><td>!CAPA</td>
<tr><td>IMAP: UW IMAP</td><td>IMAPrev1</td>
<tr><td>IMAP: Courier IMAP</td><td>IMAP4rev1</td>
<tr><td>POP3: Qpopper 4.0.5</td><td>CAPA UIDL</td>
</tr></table>

<p>If you control a post-office server that is not one of the types listed
here, please consider lending me a test account.  Note that I do <em>not</em>
need shell access, just the permissions to send mail to a mailbox the server
looks at and to fetch mail off of it.</p>

<p>I'd like to have weird things like a POP2 server on here.  Also more
closed-source servers because they tend to be broken in odd
ways. These are the real robustness tests.</p>
