MPP v3

Integrated Postfix Policy Server

We are excited to announce that MPP now features an integrated Postfix Policy Server. Our Postfix policy protocol allows Postfix to delegate access decisions to a policy server during the SMTP transaction.
Historically, MPP has been a post-queue content filter, but with this upgrade MPP can now
control whether an email is rejected pre-queue or processed post-queue. This capability, which intelligently decides between pre or post queue filterings based on the characteristics of the email, easily makes MPP the most versatile content filter for Postfix available.

Also, MPP’s powerful policy engine enables the configuration of a great number of our features on a per-policy basis. If an email arrives for a single recipient and the email has been blacklisted by the group policy or receiver, the email can be rejected pre-queue, but if a multi-recipient email arrives with two policy matches, then the email must be accepted and processed post-queue.

No other Postfix filter that we know of has this superior capability.

GUI Redesign
The MPP GUI has been completely redesigned with a new look and reorganized controls giving it a more intuitive and intelligent functionality.

Body Stripping
MPP can strip any MIME part of an email, place the content on an ftp or http server, and replace the original MIME part with a link to the file. MPP has multiple logic criteria to match based on filename, size, type, etc.

This is useful for reducing mailbox sizes by centrally storing attachments and also gives a company much better control over their confidential documents.

Thresholds
MPP can detect and report users that send too much email or too much spam in specified intervals.

Sun Java Systems Messaging Server
MPP now supports the Sun Java Systems Messaging Server, an email server that is used by many large service providers.

Logging Enhancements
MPP supports syslog for centralized logging. For our proprietary, integrated logs MPP supports splitting log files based on size, time or on reload.

Per-Policy Group RBL’s
MPP now supports real-time black hole lists on a per-policy basis. When combined with our Postfix Policy Server MPP can easily enforce per-domain SMTP policy.

New Platforms, Operating Systems and Distributions
MPP now supports FreeBSD6, Mac Intel platforms, Debian, and we have introduced new builds for newer distributions of Linux that use GCC greater than 3.3. Also, installation scripts have been significantly overhauled to ease installation.

LMTP Support
MPP now supports LMTP for per-user status for Postfix, Exim and Sun JSMS.

Minor Enhancements
Defer action for scanning error, qmail connection timers, IP identitity extracted from qmail and sendmail,
