External emails not being delivered

[polarbear]

Hi all,

We have just recently set up a DA box and are seeing some strange behaviour in regards to email.

When sending emails through Squirrelmail we find the following entries in the /var/log/maillog file (domain and IP address has been edited):

Mar 2 03:59:57 lin01 dovecot[2088]: IMAP([email protected]): Disconnected: Logged out
Mar 2 04:00:16 lin01 dovecot[2088]: auth(default): shadow([email protected],80.0.0.0): unknown user
Mar 2 04:00:16 lin01 dovecot[2088]: auth(default): passwd([email protected],80.0.0.0): unknown user

This is even though the user exists in the CP (and we're logged into webmail through that user). However, emails from Squirrelmail are being delivered as normal.

However, when sending emails from outside, those emails are not being delivered (or sometimes being delayed?). When I check the mail logs of sender's mail server, it just says

Mar 2 03:50:36 multi01 qmail: 1204426236.568981 delivery 125105: deferral: Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/

Any clues? Thanks in advance for any help!

if qmail is saying it can't establish an smtp connection that means either your exim daemon isn't running or your firewall is blocking it.

You might also want to check to make sure that dovecot has been properly installed and the correct changes made to the exim.conf file.

Without seeing real test account information at a real domain name and IP#, it's impossible to do any testing to really help you.
