The Anti-Spam SMTP Proxy (ASSP) Server project aims to create an open source platform-independent SMTP Proxy server which implements auto-whitelists, self learning Bayesian, Greylisting, DNSBL, DNSWL, URIBL, SPF, SRS, Backscatter, Virus scanning, attachment blocking, Senderbase and multiple other filter methods.

Features

• Multiple Weighted DNSBLs
• Multiple Weighted URIBLs
• Greylisting
• Weighted Regular Expression Filtering
• Bayesian
• Penalty Box
• SenderBase
• SSL/TLS
• SPF/SRS
• Attachment Blocking
• ClamAV and FileScan
• Blocking Reporting
• LDAP support
• Backscatter Detection
• V2 - recipient replacement / GUI user access rights management
• V2 - MIME charset conversion / DKIM check and signing
• V2 - DB support for all hashes / level based open plugin support
• V2 - transparent proxy support / BATV check and signing
• V2 - Plugins: archive, full attachment check and replacement, OCR
• V2 - damping (steal spammers time)
• V2 - AUTH to relay host / POP3 collector
• V2 - configuration value and file synchronization
• V2 - Block Reports design could be customized
• V2 - Razor2 and DCC support via Plugin
• V2 - SNMP support (monitoring, configuring, controll-API)
• V2 - user group import (file or LDAP or command based)
• V2 - automatic crash analyzer Hidden Markov Model
• V2 - IPv6 socket support
• V2 - word stemming (several languages) for Bayesian analyzer
• V2 - Perl module autoupdate via PPM or CPAN
• V2 - Hidden Markov Model spam detection engine
• V2 - full unicode support

Installation

Basic

Install Perl Modules and there dependencies perl-mail-spf-query, perl-email-mime, perl-net-dns, perl-email-send, perl-io-socket-ssl, perl-io-socket-inet6, perl-authen-sasl and perl-net-cidr-lite, available in the Official Repositories, perl-compress-zlib, perl-convert-tnef and perl-email-valid from AUR.

Install unzip, net-snmp and clamav, available in the Official Repositories.

armv7h architecture

To install some packages out of AUR, you have to modify PKGBUILD. If Error

==> ERROR: perl-net-smtp-tls is not available for the 'armv7h' architecture.
    Note that many packages may need a line added to their PKGBUILD
    such as arch=('armv7h').

please add armv7h to arch line in PKGBUILD.
