Helios qmail is an advanced qmail distribution based on qmail-sql. It supports SMTP, SMTPS, POP3, POP3S, IMAP, and IMAPS services. It also features antivirus and antispam filters, antispoof, SMTP-AUTH, SMTP-after-POP/IMAP, a PHP5 API, and many other useful tools.
spasm anti-spam milter
The spasm anti-spam milter is a spam filter for sendmail 8.12+ (with libmilter support). Current features include logging of rejected spam, fully virtualised settings for domains, individual whitelists, and over two dozen blacklist filters which can be set individually on a per-domain or per-email address basis (including local blacklist, rDNS resolution, HELO/EHLO verification, envelope sender address verification, numerous DNS-based lists, whitelist-only mode, tagging-only mode, and auto-blacklisting features).
MailScanner is an Email virus scanner and spam tagger. It supports sendmail and Exim MTAs, and the Sophos, McAfee, F-Prot, F-Secure, CommandAV, InoculateIT, Inoculan 4.x, Kaspersky, RAV, and Panda anti-virus scanners. It supports SpamAssassin for highly successful spam identification. It is specifically designed to handle Denial Of Service attacks. It is very easy to install, and requires no changes at all to your sendmail.cf file. It is designed to be lightweight, and won't grind your mail system to a halt with its load. It can be integrated into any email system, regardless of the software in use.
BitDefender AntiVirus for qmail
BitDefender for qmail is a powerful antivirus software for Linux mail servers, which provides proactive protection of message traffic at the email server level, eliminating the risk to the entire network that could be caused by a negligent user. All messages, both sent and received, are scanned in real time, avoiding the possible infections and preventing anyone from sending an infected message. BitDefender claims 100% detection rate for all viruses in the wild (ITW) through its powerful scanning engines certified by the most prestigious testing labs (ICSA in February 2003, Virus Bulletin 100% in June 2003 and CheckMark in August 2003).
Animail is a multiserver POP3/APOP/IMAP4Rev1 (with or without SSL) mail retrieval utility. It features an advanced filtering system based on blacklisting, whitelisting, or a combination of both. It is possible to send an autoresponse which prompts people to reply and add themselves to the 'autoaccept' file. It also allows filters based on a regular expression which matches against the email headers. (If a message is filtered, only the header is downloaded, not the entire body.) Animail also features download ordering options. For example, you can configure it to download the smaller messages first. Different delivery options are available, including mailbox, maildir, local SMTP, and pipe to command.
Mailfilter is a flexible utility to get rid of unwanted spam mails, before having to go through the trouble of downloading them into the local computer. It offers support for one or many POP3 accounts and is especially useful for dialup connections via modem. You can define your own filters (rules) to determine which e-mails should be delivered and which are considered waste.
IMAPFilter connects to remote IMAP mail servers and processes messages according to defined filters (rules). It is intended to be executed before a user accesses his/her mailboxes.
SpamAssassin is a mail filter that uses a wide range of heuristic tests on mail headers and body text to identify spam. Once identified, the mail can then be optionally tagged as spam for later filtering. It provides a command line tool to perform filtering, a client-server system to filter large volumes of mail, and Mail::SpamAssassin, and a set of Perl modules that implement a Mail::Audit plugin0 (allowing SpamAssassin to be used in a Mail::Audit filter, a spam-protection proxy POP/IMAP server, or almost anywhere).
CleanPOP logs into a POP3 server and deletes messages which have had a local (or remote) spam header added to them, as well as messages that have been on the server for longer than a user-configurable amount of time. It helps you keep your POP3 mailbox clean, so you can use Webmail or download messages from your POP3 server to other machines without having to deal with spam. It correlates messages from your local mbox file with messages on the POP3 server, which means that you can use local antispam solutions to clean your remote inbox, and it never deletes an unfetched message, unlike other mail expiration scripts.
Inflex is an email scanner which encapsulates your existing sendmail server setup. It scans both incoming and outgoing email and it does not alter your current /etc/sendmail.cf file. It can scan for email viruses, unwanted file types (eg. EXE, BMP, MPEG) and file names (eg. prettypark.exe). It can also be used to scan for text snippets within emails and to insert disclaimers into outbound emails.
