Hi @stsinc
In addition to the proposal of @rprengel, you may want to take a look at the ruleset “Check Email”.
I have never used it before, but its “inline help” says:
The basic function of this check is to log in into an IMAP or POP3 mailbox to monitor whether or not the login is possible. A extended feature is, that the check can fetch all (or just some) from the mailbox and forward them as events to the Event Console.
Looks like, it’s possible. 
HTH,
Thomas
