RAA - sendmail-milter

Sendmail::Milter provides users with the ability to write mail filters in Ruby that tightly integrate with sendmail's mail filter API.

It is a Ruby port of the excellent Sendmail::Milter Perl module by Charles Ying.

With this module, you can define and register Ruby callbacks with the Milter engine. This module calls your ruby callbacks using interpreters from a threaded persistent interpreter pool. Milter contexts are presented using an object-oriented style interface for performing operations on a Milter context.
