Error sending message

[leonroy]

I get a really long delay when sending a message after which the error appears:

"A network service error has occurred"

I've searched all over the forums for a solution to no avail.

It would help if you let us know which version of ZCS you are running ? Also, any error messages in /var/log/zimbra.log ?

I was using 5.0.9 when I saw this error. I upgraded to 5.0.10 in case it fixed it.

In zimbra.log I see:

In case it helps anyone I found that running zmfixperms (in /opt/zimbra/libexec) and then chown zimbra:zimbra /opt/postfix/conf/main.cf and restarting zimbra fixed the issue.
