Then try out Scientific Linux - https://www.scientificlinux.org/ . I've tried out all other RHEL alternatives, but SL 3.03 is one the cleanest and nicest alternatives.
L is a Linux release put together by various labs and universities around the world. It's primary purpose is to reduce duplicated effort of the labs, and to have a common install base for the various experimentors.
The base SL distribution is basically Enterprise Linux, recompiled from source.
Our main goal for the base distribution is to have everything compatible with Enterprise, with only a few minor additions or changes. An example of of items that were added are Pine, and OpenAFS.
Our secondary goal is to allow easy customization for a site, without disturbing the Scientific Linux base. The various labs are able to add their own modifications to their own site areas. By the magic of scripts, and the anaconda installer, each site is be able to create their own distributions with minimal effort. Or, if a users wishes, they can simply install the base SL release.
but the Messaging Server had problems. Since it hasn't been update since Sun abandoned the IPlanet joint venture, we tried to use various plugins and hacks to keep it from being used as an open relay, or getting spam floods, but no luck. We ended up abandoning the project, but we may be re-doing it in Open Exchange.
Not quite true. The Messaging component is by far the best part of this solution. We still continue to use iMS 5.x (iPlanet Messaging Server from Sun). By default there is no open relays and it supports RBLS. The iMS 5.2 p2 version also supports SpamAssassin/Brightmail. Much of the code for this platform comes from PMDF http://www.process.com/ and these people "know" mail servers.
The stability, security and scalibility of this messaging server is amazing!!! In fact, bigger ISP's (such as Shaw, still continue to use iMS on their backend mail servers).
The messaging server contains:
- SMTP Server (this was mainly from code from pmdf)
- Web Server (this is a stripped down, yet quite powerful version of the Netscape/Sun (iPlanet) Web server which runs ME (or Messaging Express). It's the webmail component of this platform. Extremely fast, efficient and can run circles around any PHP/JAVA webmail solution.
- Mail Store (this is derived from work on cyrus imapd). There are many utils that allow you to backup, manage, and export users (which are kept in the LDAP db)
If given a choice, I would pick iMS (or in this case Netscape/Redhat's OpenSourced solution anytime!!). If you browse around to the public mailing list archives located at http://ims.balius.com/, you'll see folks who have mail volume of over 10 million email/hr.
This is by far the most fantastic piece of software which has really never been marketed properly.
