mailspy
mailspy makes it possible for you to monitor the activies of your sendmail mail server. Most mail analysis programs will only report the sender and recipient of a mail and its size. mailspy records the sender, recipient, the subject line and the names of the attachments. mailspy can now be deployed to archive copies of selected mails (both incoming and outgoing). Access to these mails is provided with IMAP.
