Sendmail::Milter provides users with the ability to write mail filters in Perl
that tightly integrate with sendmail's mail filter API.
With this module, you can define and register Perl callbacks with the Milter
engine. This module calls your perl 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.
ProxSMTP is a flexible tool that allows you to reject, change or log
email based on arbitrary criteria. It accepts SMTP connections and
forwards the SMTP commands and responses to another SMTP server. You
need to be able to write the filtering scripts that integrate it with
your particular needs.
PEAR::MIME_Type provides functionality for dealing with MIME types.
* Parse MIME type.
* Supports full RFC2045 specification.
* Many utility functions for working with and determining info about types.
* Most functions can be called statically.
* Autodetect a file's mime-type, either with mime_content_type() or the 'file'
command.
It can split messages inside a Mbox, return the number of messages, return,
update or remove an specific message or add a message on the Mbox.
PEAR classes to deal with creation and manipulation of MIME messages.
Class to handle mail queue managment.
Wrapper for PEAR::Mail and PEAR::DB (or PEAR::MDB/MDB2).
It can load, save and send saved mails in background
and also backup some mails.
The Mail_Queue class puts mails in a temporary container,
waiting to be fed to the MTA (Mail Transport Agent),
and sends them later (e.g. a certain amount of mails
every few minutes) by crontab or in other way.
qmqtool is a qmail queue manipulation program geared towards the
viewing and safe modification of the contents in a qmail queue.
Features include finding abusers, sorting messages by sender/sender's IP,
showing stats, requeue messages, queue consistency check, queue
backup/restore, and others.
postfix-policyd-spf-perl is an RFC-4408-compliant SPF policy service for
postfix written in Perl.
This is python module for RFC 5451 Authentication-Results Headers
generation and parsing.
It also supports Authentication Results extensions:
RFC 5617 DKIM/ADSP
RFC 6008 DKIM signature identification (header.b)
RFC 6212 Vouch By Reference (VBR)
draft-kucherawy-dmarc-base-00 DMARC
renattach is a fast and efficient e-mail stream filter written by Jem
Berkes. It can rename or delete potentially dangerous attachments or
even eliminate entire messages to help sites deal with resource strains
caused by virus floods. Unlike conventional virus scanners, there are no
specific virus or worm definitions. Instead, attachments are classified
based on file extension and executable encoded body content.
Features
- Fast, efficient, lightweight, little overhead, pure C code
- Recognizes both MIME and uuencoded attachments
- Compliant with RFC2047 and RFC2231, handles encoded filenames
- Capable of reading filenames inside ZIP archives, on the fly
- Can rename or delete attachments, or kill entire messages
- Can detect executables that carry DOS/Windows signature
- Supports list of banned filenames (great for handling floods)
- Simple pipe/stream operation; can be used within many filtering systems
- Can be used directly as a content_filter for Postfix MTA
- Can be installed as a local delivery agent for Sendmail MTA
