SmartPOP2Exchange helps you to connect your existing POP3 and IMAP accounts to any SMTP or Exchange mail server. The all-rounder works in the background: SmartPOP2Exchange downloads all messages from various accounts and forwards them to your Exchange or any other SMTP server. It also supports downloading of RSS Feeds and delivers them as mail messages to specified accounts. The user-friendly configuration tool is based on the Microsoft MMC.
Unsolicited mails are filtered reliably: SmartPOP2Exchange includes the popular spam filter, SpamAssassin, that is already preconfigured. SpamAssassin achieves a detection rate of over 99% with its various techniques, like Blacklist server requests, Bayes filter, static rules and many more. As SpamAssassin is able to train itself automatically, its efficiency increases the longer it is in use. You can decide how detected spam messages will be processed (tag, move, delete, etc.). Nearly all installed virus scanners can be utilized by SmartPOP2Exchange in order to identify mails infected by a virus or Trojan. The virus scanner ClamAV (integrated in the Enterprise Edition) can also protect you from phishing mails.
SmartPOP2Exchange also provides a flexible and powerful set of rules. The conditions and actions can be applied in any combination,
