Generally deletion/scrubbing e-mail messages is not something that businesses should be doing. However, there may be a requirement for this functionality when security is a concern.

PerfectMail uses a US DoD compliant process for scrubbing and removing e-mail messages.

DoD 5220.22-M(ECE) is a seven pass overwriting wipe standard: first and second passes - with certain bytes and with its compliment, then two passes with random character, then two passes with character and its complement and the last pass - with random character.

Enable File Scrubbing by the following steps:

1. Enable the feature on: Server Admin => Server Settings, Other tab; enable e-mail shredding and deletion.
2. Give permission to a user to Shred/Delete a message on: Server Admin => Users; select a user; Permissions tab; enable Shred/Delete messages.
3. Now you can Shred/Delete messages in the E-mail Activity pages.
4. A log entry of the deletion is made on: Server Admin => Audit Log and a record of the message remains in the activity log; but all content is scrubbed and removed.
