IceWarp Takes the Linux Mail Server Plunge - page 4

Examining Merak

Whether running Linux or Windows, dealing with e-mail viruses and spam is a universal concern. In all but its least expensive (standard edition) incarnation, Merak Linux Mail Server includes anti-virus and anti-spam modules. The anti-virus package integrates AVG7 from Grisoft, which provides the virus definition updates. The anti-spam package is put together by IceWarp itself and includes SpamAssassin (with Sender Policy Framework, Spam URI Realtime Blocklist, Bayesian filters), DomainKeys, Reverse Black List, black and white lists, and content filters. IceWarp updates the spam lists and claims "near 100 percent accuracy." We particularly liked the range of ways to respond to spam mail, including spam folders automatically created for each user, changing the spam subject line, deletion of spam, rejection of spam, and a challenge and response mechanism. We consider the anti-spam module exceptional.

These days, e-mail is hardly alone in the Internet communications game. Although Merak Linux Mail Server does not get into multimedia and telephony, it does provide an attractive range of companion modules for the mail server: The Jabber-compliant IM client offers connections to major IM services, including AOL and MSN. There is also a WebMail client module, a usable GroupWare module that includes calendar and group functions that can integrate with Microsoft Outlook, and an FTP server.

In the sendmail and Postfix world of Linux, IceWarp Merak Linux Mail Server competes best where it would be most used--with ISPs and enterprise communications. In these contexts, the integrated modules and high-performance server, combined with professional service and support, justify the (moderate) pricing.

Pros: Performance and large installation orientation combined with the solid integration of important (anti-virus, anti-spam) and useful (IM, workgroup, FTP, WebMail) modules.
Cons: Limited support for various Linux distributions; More and better Linux-specific documentation is needed; For some, the fact that this is Linux version and not open-source is a negative in itself.
