Greylite

Greylite is a greylisting solution for qmail. Greylite may be preferred to other greylisting solutions because:

it does not require patching qmail, it is simply plugged in the top of the qmail chain; thus is works smoothly with already-patched installations
it does not depend on bigger RDBMSs like PostgreSQL or MySQL, it is self-contained because it uses sqlite

Greylite is easy to setup and maintain, and it is small and fast.

Amavisd-new

amavisd-new is a high-performance and reliable interface between mailer (MTA) and one or more content checkers: virus scanners, and/or Mail::SpamAssassin Perl module. amavisd-new is written in Perl, ensuring high portability, reliability and maintainability. It talks to MTA via (E)SMTP or LMTP protocols, or by using helper programs. No timing gaps exist in the design, which could cause a mail loss.

It is normally positioned at or near a central mailer, not necessarily where users’ mailboxes and final delivery takes place. If looking for a per-user and low-message-rate solution to be placed at the final stage of mail delivery (e.g. called from procmail or in place of a local delivery agent), there may be other solutions more appropriate.

When calling of Mail::SpamAssassin (SA) is enabled, it calls SA only once per message regardless of the number of recipients, and tries very hard to correctly honour per-recipient preferences, such as pass/reject, check/nocheck, spam levels, and inserting spam-related mail header fields.

amavisd-new benefits from the use of Perl module Net::Server, which offers a fast pre-forked multichild process control. amavisd-new provides rfc2821-compliant SMTP server, rfc2033-compliant LMTP server, SMTP client, and generates rfc3462/rfc3464-compliant (ex rfc1892/rfc1894) (non-)delivery status notifications.
This makes it suitable for mail anti-virus and/or anti-spam checking on a busy mail gateways that care for reliability and standards compliance.

amavisd-new grew out of amavisd(-snapshot) (which in turn is a daemonized version of amavis-perl), but through three years of development turned into a separate product, hardly resembling its origin. The code is several times the size of its predecessor, yet faster in throughput, richer in features, compliant to standards, includes optional support for spam detection, and makes virus scanning optional and easier to adjust/extend. Compatibility with helper programs from amavisd(-snapshot) is retained.

All modifications since the original amavisd done by Mark Martinec, with contribution of ideas, patches and reports from the amavis-user mailing list community and individuals.

What’s New in This Release:

· Regular expressions were simplified to avoid Perl crashing on very long degenerated addresses in a header.
· Parsing of header field names is stricter to avoid duplicating a Subject header field under rare circumstances.
· Policy bank name from AM.PDP protocol is now untainted to avoid SQL errors.
· Handling of status EAGAIN in SMTP client code was improved.
· The number of arguments to a file(1) utility now obeys a POSIX program argument space limit.
· Sprintf format for conversion of 64-bit values was fixed.
· AV entries for F-PROT fpscan and fpscand were added, and a BitDefender bdscan entry was updated.

Qpopper is the most widely-used server for the POP3 protocol

Qpopper project is the most widely-used server for the POP3 protocol (this allows users to access their mail using any POP3 client). Qpopper supports the latest standards, and includes a large number of optional features. Qpopper is normally used with standard UNIX mail transfer and delivery agents such as sendmail or smail.

Qpopper’s goals are: security, stability, safety, features, and performance.

The 3 and later code base has multiple levels of protection again common security vulnerabilities, so even if there is a bug at one level, the other levels can protect against an exploit. Stability means running without crashing or other problems. All bug reports are reviewed and taken seriously.

Safety means protecting the user’s mail. Qpopper takes extra precautions to guard against spool corruption, even if there is a system crash or power failure during an update. Qpopper provides a large number of features, such as bulletins, support for wireless devices, APOP, integration with packages such as Kerberos, drac, etc.

Qpopper strives for the maximum possible performance consistent with safety. You can also tell Qpopper when it is running in an environment where some precautions are not required, resulting in extra performance (for example, if users do not access mail using shell accounts).

This server is fully compliant with RFC 1939 (which defines the POP protocol) and RFC 2449 (which defines the POP extension mechanism and the extended response codes), and works with all known POP3 clients.

Qpopper also supports Kerberos V4 and V5 if enabled.

Here are some key features of “Qpopper”:

· Faster start-up (1,000 times faster, in many cases)
· Reduced I/O at session end (one-third less!)
· TLS/SSL (allows authentication and email to be strongly encrypted between any TLS/SSL-enabled mail client and Qpopper 4.0.5; requires TLS/SSL)
· Plus all the great features of Qpopper 3.1 (including full sources)
· Most compile-time options now are available at run-time
· Easier administration

Exim is a message transfer agent (MTA) for Unix systems

Exim is a message transfer agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet.

Exim is freely available under the terms of the GNU General Public Licence. In style it is similar to Smail 3, but its facilities are more general.

There is a great deal of flexibility in the way mail can be routed, and there are extensive facilities for checking incoming mail.

Exim can be installed in place of sendmail, although the configuration of exim is quite different to that of sendmail.

Mozilla Thunderbird

Mozilla Thunderbird is a full-featured email, RSS and newsgroup client that makes emailing safer, faster and easier than ever before.

It offers some advantages over other mail clients, including junk mail classification. Built from Mozilla code, Mozilla Thunderbird uses Gecko, the most standards-compliant rendering engine in existence.

In addition to the feature set found in Mozilla Mail, Thunderbird has several new features and improvements to make your mail and new experience better.

Here are some key features of “Mozilla Thunderbird”:

· Adaptive Junk Mail Controls
· RSS Integration
· Saved Search Folders
- Saved Search Folders display messages based on previously set search criteria. For example, instead of filtering messages into a new folder, you can create a Saved Search Folder that lists all the messages received from a certain person over the past 30 days, even if those messages are stored in different folders and subfolders.
· Global Inbox Support
- POP3 users can now combine all of their POP3 accounts into a single global inbox under local folders.
· Message Grouping
- You can now group messages in a folder by attributes such as date, sender, priority or a custom label. For instance, a folder grouped by date will group messages from today, yesterday, last week, etc. into self-contained groups in the message list pane. (View > Sort By > Grouped By Sort)
· Privacy Protection
- In order to help protect your privacy, Thunderbird now automatically blocks remote image requests in emails from senders you don’t know.
· Comprehensive Mail Migration from other Mail Clients
- Switching to Thunderbird has never been easier since Thunderbird can now migrate all of your email data including settings, mail folders and address book data from common mail applications such as the Mozilla 1.x Suite, Outlook Express, Outlook and Eudora.
