Need to find a message in the logs

[Jbrabander]

Here's what I've got going on. Hope someone can guide me through it.

Is it possible to go through the Zimbra logs to find out if someone has sent us an email? I've got the sender's email address. But I'm not sure what log to use or how to run the search. We need to see if they actually sent us an email or if they're pulling a fast one on us.

Search the MTA log file for the email 'from' address, their server IP or their server name. Don't forget the log file may have been rotated.
