Mail Server Bounce Issue :(

[pandesa]

Hey folks, I have a centos mail server running that is set up to use SSL over postfix/dovecot. When I try and login to an email via thunderbird on a windows machine I can receive all mail inside the maildir, but I am unable to send!

my maillog shows:

Jun 27 18:29:43 host26 postfix/smtpd[23217]: connect from dsl093-170-078.sfo4.dsl.speakeasy.net[66.93.170.78]
Jun 27 18:29:44 host26 postfix/smtpd[23217]: lost connection after UNKNOWN from dsl093-170-078.sfo4.dsl.speakeasy.net[66.93.170.78]
Jun 27 18:29:44 host26 postfix/smtpd[23217]: disconnect from dsl093-170-078.sfo4.dsl.speakeasy.net[66.93.170.78]

And if I try and do a local test I get:

Jun 27 17:55:22 host26 postfix/cleanup[22732]: 8055E443B9E: message-id=<20110628005516.8055E443B9E@mail3.sharevault.ne t>

Anyone got any suggestions as to whats going on? im sure its just a newbie mistake...

also, the local user "superadmin" DOES exist.

What's the output of

postconf -n

?

Did you use a tutorial to set up the server? If so, which one (URL)?
