Hello List,

I'm new to dovecot.  I have sucessfully configured dovecot with just
virtual users on a centos linux box to my satisfaction; I can connect
with TLS with disable_plaintext_auth = yes.  This dovecot is also
version > 1.   Can't post exact version right now but it's what comes
with Centos 5.4.

On a Ubuntu 9.10 box here, I cannot connect with TLS (port 110) but I
can connect with plain SSL (port 995).  The config files between
centos and ubuntu boxes are the same except for minor details.

The following is the log entry

Feb 17 21:38:18 ubuntu dovecot: pop3-login: Disconnected (no auth
attempts): rip=, lip=

The output below is from a binary compiled from source.  I have also
tested with 1.1.11 (that I get from apt-get install) with the same
config file.
I have tested ubuntu with both Thunderbird 3 and thunderbird 2.
I have also searched google as well as dovecot website.
