The traffic could be around 1000 user accounts and around 200 users accessing simutaneously. My vote will go to Courier every time. Its architecture and configuration is similar to Qmail, but it provides a full mail suite (SMTP, POP3, IMAP, webmail, fax, mail filtering) which can be used as a whole or just the parts you like. If you run most any other modern SMTP server (such as Postfix), you'll probably use Courier's IMAP server with it. Give the suite a try. It's easier (IMO) to configure everything once, than to do it once for each piece of your mail server. I use the Courier system in my work environment, supporting about 1000 users. Our system uses an NFS backend and a cluster of identical mail servers. Each of the three mail server is an 800Mhz P3 with 512MB of RAM. Each one runs the Courier suite, plus SpamAssassin and RAV antivirus. The system is designed to scale linearly; if the load becomes too great, we just add another server and rsync the filesystem of an existing server onto the new one. Let me know if you're interested in more details. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list

Re: Linux Mailserver
Hi, PostFix seems to be able to handle hundreds of users on a low-end machine. I highly recommend it as a mail server.

I use it in a smaller enviornment but It seems to be quite scalable. I highly recommentd you subscribe to the postfix List though. They helped me though some baffling configuration issues. However,.besure to use filters on your email client. 80-100 meesages/day is the norm. For reference, I subscribed on 4-22 and currently have 5500+ messages. It seems to have a very large installed base and is being actively developed.

Re: Linux Mailserver
Hi Joseph, I think that exim mail server is a great mail server and is quite good with loads. I have previously used Dell PE2500/2650 for the mail servers and PE1550 for mail relays. You can outfit them to suit your price range. Cheers, Aly.

Re: Linux Mailserver
Hi, Another important thing to consider when choosing a mail server, is that it has a large user base, from which you can ask questions, and bounce ideas off. PostFix seems to have a very large user base, which makes it a good choice, IMO.

PostFix seems to have a very large user base, which makes it a good choice, IMO. Richard I have to admit, I'm currently testing postfix on my inbound server. So far, so good! Configuring postfix was alot easier than sendmail and the postfix list server is quite helpful. I especially like postfix's ability to test the HELO greeting from the remote MTA. Fricken spammers are always extracting my servers IP address or canonical name from the initial 220 response and responding with the same HELO greeting. I can't beleive how many spammers that this one test has rejected (prior to the DATA portion being sent) in just 48 hours. Unless something major happens during my testing phase, I'll probably stick with postfix.

The traffic could be around 1000 user accounts and around 200 users accessing simutaneously. I think you're asking two questions - one about the MTA, and one about the user-accessible mail spool. As for the MTA issue, you can use any of Sendmail, Postfix, or a few others. We use sendmail at work and push through all the external e-mail for 5,000 employees (about 20K messages) through a pair of P II/450 systems and the systems don't even break a sweat. For the user-accessible spool, are you looking at POP, IMAP, or web-based e-mail? You can do both POP and IMAP on a low-end server and any recent generation system isn't going to have any issues at all with the small workload you're talking about. For web-based e-mail access, you might have some issues, but I doubt it. I expect that a package like Squirrelmail will handle that load without a problem, again, on a recent system. Anything in the P4 XP+ class will do. On a lower-end system, I'd probably go with a dual cpu myself - something like a P3/500 or a dual-P3 Xeon system. On any of the configs, go with a minimum of 256MB and preferably 512MB+. -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED] Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
