Fellow users,

This is just a heads-up to let the list know that I'm still unable to get ANY sort of pop3 or pop3s authentication to work with Dovecot.

Just as a sanity check, I set up an entirely separate system, running FreeBSD 6.1 production, postfix 2.3, and Dovecot 1.0rc2, as a testbed. I got the exact same problem that I had with the NetBSD 3.0 production server, specifically that Dovecot refuses to authenticate a user with either basic pop3 or pop3s.

The way I see it, I may as well try to get basic pop3 working first. If it doesn't, pop3s will never work.

This first quote is taken from the mail client (Pegasus) trying to establish a regular, unencrypted pop3 session.

As you can see, the user ID of 'kyrrin' is getting passed as just that, and Dovecot at least seems to recognize it. I say this as a prefix to the next log clip, which will be the corresponding entry from /var/log/maillog, in which the user name is being presented (for whatever reason) in FQDN format.

Note that pam was added just as an experiment. It failed too, despite the presence of a 'dovecot' file, containing the following, in /etc/pam.d

This would be the /var/log/maillog entry corresponding to the above-referenced Pegasus session.

This next bit is the auth default section of my dovecot.conf file. Other sections, or the entire file, can be posted upon request.

I've posted a similar note to bsdforums, in the hope that someone there is (successfully) using Dovecot with pop3 and pop3s.

Thanks in advance for any assistance. I'm really starting to get seriously upset about this, enough to give thought to qpopper over Dovecot.
