MailMax 5.5 for Windows 2000/XP/NT4 is an award-winning, high performance, scalable email server that supports SMTP, IMAP4 and POP3 protocols. A multithreaded application, with multiple CPU support, MailMax 5.5, highly expandable, is driven by an industry standard Microsoft SQL 2000 database (bundled free with MailMax), and provides you with lightening speed, strong security and reliability. MailMax's NEW TCP/IP GUI allows server administration from any Internet connected server and lets you "SPY" and monitor (complete with live graphs) your server activity remotely from any Windows desktop. The 'housekeeping' feature will keep your email server clean and free of clutter. It can delete old mail from inactive users based on activity or message age! Our powerful WEB Admin module written in ASP.NET, allows you to define domain administrators so they can maintain their own accounts and a host of other user options. Secure and versatile, MailMax 5.5 provides superior anti-spamming options: Content filters work on the system level, domain level, as well as the user level. MailMax also offers optional integrated virus protection from Avast and Sophos as well as command line virus scanning. A new feature in 5.5 is 'Tarpitting'. This allows administrators to scan for unsuccessful attempts by outside users to send to non-existing users on the server. You can configure MailMax to specify the number of failed attempts, before the offending IP address is disconnected during that session. Administrators have the power to check connecting IP addresses against open relay/spam databases on the internet. Our open architecture allows you to define open relay databases of your choice. This is used to greatly reduce the amount of inbound spam. MailMax allows you to setup blocks using IP addresses and/or email addresses. You can also specify "Known and Trusted IP's" which are IP's of your choice that can use your SMTP server to send outbound email. All this and much more!
