I have a MiaB box with about 30 email boxes. This errror pops up in /var/log/mail.err but with no other information. How can I trace it and fix it ? I believe people are not receiving their emails when this happens.
This is when a user sends a message with an attachment to another mailbox on the same server:

Any ideas what’s happening here ?
Looks like there’s a issue when an email has an attachment.
Disabling ipv6 on centos 6.5 seems to have removed this issues.
No idea, but did you check free disk space? You could also try re-running mailinabox in case any permissions got broken.
