MTA stops delivering mail. Imap server won't accept logins.

[adobrin]

Not sure exactly what happened.

But right now, the MTA is holding alll incoming mail in spool/deffered; and the imap server won't accept login.s (returns permission denied.). The web client is connecting ok.

Can't seem to find any errors in the log files, where should i start looking?

ps -ef | grep tomcat

See if you tomcat is running.

examine /opt/zimbra/tomcat/logs/catalina.out to see why tomcat may have stopped.

If tomcat is indeed running, then it is time to see if for some reason tomcat may have deadlocked. So if process is running, and telnet ot ports 7025 and 7143 hangs, please do a kill -3 on the tomcat JVM process, and post the stack trace dumped to catalina.out.

tomcat is running.

[root@dork zimbra]# ps -ef |grep tomcat

[anand]

did you try the telnet steps?

restart yields:

catalina.out has a bunch of sql, no errors that i can see.

again, the web interface is working fine.. its just not delivering mail to the mail store; and imap is not allowing logins.

[adobrin]

sorry.. what do you mean telnet steps?

postfix is accepting mail, and the machine is accepting connections on :143; just not authorizing connection.

[adobrin]

where is the postfix maillog hidden?

[adobrin]

ok, I removed the DNS flags from the admin UI MTA tabs (in both server and global), and all the deferred mail has now been delivered. i'm also getting incoming email from the internet.

the IMAP server is still denying connections though. i'm assuming this is a problem with saslauthd.. any suggestions?

[anand]

our IMAP server doesn't use SASL to authenticate. The default setting is to disallow clear text logins. You probably need to toggle that - or go to the IMAP/SSL port.

[adobrin]

Cleartext logins are already allowed, and it is currently set to connect over SSL. That shouldn't be a requirement though, right? both 143 and 993 are open and useable?


the slapd run string includes "ldap://:7389" with no host, could that be causing the problem?
