I think we have a pc on our network that is sending out spam due to a virus but I can't figure out how to track it down. I have poured through some log files trying to track it down using the Zimbra log and the audit log. We have been placed on some blacklist and we are deleting out several thousand deferred emails a day due to this.
Is there any other log file that would track this down better? Any other tips or tricks?
