Mail Audit Tool is a mailbox interrogation and reporting product. Given the name of a user's mail file or several mail files, it produces a report showing all attachments by type and size, letting an admin remove any attachment and leave a message in its place explaining why it was removed.
The Mail Audit Tool is priced per mailbox and per scan. So, if you need to scan a user's mailbox, you can buy a single-mailbox, single-scan license of Mail Audit Tool for US$1.90 and license new scans as you need them.
