Yesterday morning, our server started deferring messages with lost connection with[] while sending end of data -- message may be sent more than once.
We were running 5.0.9 on Centos 5. We narrowed it down to amavis - either the spam or virus, so thinking we needed to upgrade, we upgraded to 5.0.18. The server is still deferring messages. We edited the file to disable the spam checking, and restarted zimbra and the messages are going through. Anyone have any ideas on how to check where the spam filter is having a problem?
Thanks in advance for any help.
