MIMEDefang

Perl-scriptable email filter that plugs into Sendmail or Postfix to inspect, modify, or reject MIME messages.

Servicefree

MIMEDefang is a Perl-scriptable email filter that hooks into Sendmail's Milter interface or Postfix to inspect every message once per SMTP connection, letting administrators delete or convert attachments, run spam and antivirus scanners, and bounce mail during the transaction itself. It is built for mail server administrators who need programmable, connection-level filtering policy.
