What is MIMEDefang?

MIMEDefang is a framework for filtering e-mail. It uses Sendmail's "Milter" API, some C glue code, and some Perl code to let you write high-performance mail filters in Perl.

People use MIMEDefang to:

  • Block viruses
  • Block or tag spam
  • Remove HTML mail parts
  • Add boilerplate disclaimers to outgoing mail
  • Remove or alter attachments
  • Replace attachments with URL's
  • Implement sophisticated access controls.

You're limited only by your imagination. If you can think of it and code it in Perl, you can do it with MIMEDefang.
