CommuniGate Pro 3.4

The Internet’s killer apps have always been email programs, but users’ demands for more features, better security, and speed are tough to meet for Mac administrators using traditional mail-server packages. Mac OS X opens up the Macintosh to powerful mail servers previously available only on other platforms. One of those mail servers is Stalker’s CommuniGate Pro 3.4, a power app with advanced features such as encrypted-mail transfer, Web-based administration and email access, list management, and spam and virus protection. With its rich feature set and scalability, CommuniGate Pro turns the Macintosh into a world-class mail-serving platform. Don’t confuse it with CommuniGate, Stalker’s older, Mac-only program; CommuniGate Pro is a different product that until recently ran only in Windows and Unix. Version 3.4 is the first commercial release to run on the Mac in any capacity, and it runs only in OS X. Secure services
Installation is a snap, and the package is easy to administer via any Web browser. Unlike other Web-administered programs, however, CommuniGate Pro supports Secure Sockets Layer (SSL) encryption out of the box; you don’t need to get a certificate – meaning you can administer CommuniGate Pro from anywhere. CommuniGate Pro’s line-up of services is extensive. The program supports most mail protocols – including SMTP, POP3, and IMAP4 – as well as the latest SSL encryption and Simple Authentication and Security Layer (SASL) authentication extensions. It can serve any number of domains, and it gives users their own Web sites. An extensive rule-processing engine allows you to set up mail pre-processing to filter and prioritize mail. Built-in spam protection prevents hackers from abusing your mail server, and lets you use DNS-based spam-blocking services. With its support for content-filtering plug-ins, you can use third-party virus scanners on incoming mail. One of CommuniGate Pro’s most impressive features is its scalability: you can support a few thousand users on a small Macintosh (such as an iMac) running Mac OS X, tens of thousands on a large OS X server, or millions on a multiserver cluster. Even the smallest CommuniGate Pro configuration includes access to the entire suite of standard features. CommuniGate Pro uses SSL encryption to protect mail from interception. SSL encrypts POP3, IMAP4, and Web-user sessions, as well as SMTP sessions between CommuniGate and distant mail servers. This latter protection requires the cooperation of off-site mail-server administrators, so it’s most useful for setting up enterprise-email exchange.

OUR VERDICT

CommuniGate Pro 3.4 is a sophisticated mail server with loads of features, but it’s easy to set up and maintain. Its many security options help you keep email private, and extensive spam protection lets you minimize the amount of email noise your users must endure.
