The Mail Monitor is a program enabling you to monitor incoming and outgoing mail traffic to and from your mail server and clients. It tracks, displays and logs incoming and outgoing SMTP sessions, POP sessions and sent/received e-mails.
It can store incoming and outgoing e-mail in a separate directory independent of mail clients. Finally, MailMonitor keeps a trace of all e-mail related session traffic (at packet level) enabling you to explore what is going on in your e-mail environment.
