I think all of the reported bugs are again fixed in CVS, so I made a tarball of it. I'd like to hear if there's any problems with it. Here's the most important changes:

v0.99.8 2003-02-xx Timo Sirainen <tss@iki.fi>

* NOTE: Configuration file has changed a bit: auth_userinfo was
  replaced by userdb and passdb. *_port were merged into *_listen.
  Disabling listening in imaps port is now done by changing protocols
  setting.

+ Fully featured POP3 server included. Disabled by default.
+ Support for LITERAL+, MULTIAPPEND and UNSELECT extensions.
+ Internal API cleanups made Dovecot faster and take less memory
+ auth_verbose logs now all authentication failures
+ Support for Solaris 9 sendfilev() (not really tested)
- COPY now behaves as RFC2060 says: "If the COPY command is
  unsuccessful for any reason, server implementations MUST restore the
  destination mailbox to its state before the COPY attempt."
- maildir_copy_with_hardlinks = yes was broken.
- mboxes in subfolders weren't selectable.
- STORE didn't accept multiple flags without () around them
- PLAIN SASL-authentication was a bit broken.
- IMAP dates were parsed a few hours wrong
- If auth/login process died unexpectedly at startup, the exit status
  or killing signal wasn't logged.
- mbox parsing might have crashed sometimes
- Next command after STARTTLS was ignored which left the connection
  stuck sometimes
- STATUS command removed \Recent flags from messages
- Several bugfixes to SEARCH command, especially related to multiple
  search conditions
