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.
A complete description of MIMEDefang may be found in the PDF presentation slides.
