The Mail::Toaster includes nearly every feature you could imagine in a modern email solution. Here's are a few of the most compelling features:

Security - Mail Toaster supports secure connections from the email client (via POP3, IMAP, SMTP, and webmail) to the server. If the remote (destination) email server supports it, we also encrypt the email as it travels across the public Internet from server to server. If you use two Mail::Toasters and your email clients are configured to use SSL, you have a fully encrypted path from the email sender to the final recipient.

Robust Filtering - Mail Toaster has sophisticated filtering capabilities built right in. A default installation blocks all viruses and will detect 85% of the spam. With a little bit of training, it is reasonable to expect 99% spam filtering accuracy.

Flexibility - Mail Toaster provides an extremely flexible framework to allow you to build your email system your way. This flexibility makes it easy to migrate existing systems to Mail::Toaster and also allows Mail::Toaster to work in diverse environments and OS platforms.

Support - There is a thriving and active support community available on the mailing list. The web forums are also frequented by quite a few helpful folks. If you need more support than folks are willing to provide, commercial support is available.
