Max Email Users
We are running FreeBSD 4.6 on a PIII 600 with 256 Meg RAM as our mail server. At what point (how many users) will we start running into trouble (have problems allowing us to send and receive email?)

I suppose it's possible that disk space would give you trouble before anything else. Kevin Kinsey, DaleCo, S.P.

Thanks. Well that depends on exactly how your users are using the mail server. If all they're doing is accessing it via smtp/pop then the answer would be GOBS of users. Sorry for that highly technical answer, but I honestly don't know how many users a 600mhz PIII will support, but I know it's hundreds at the very least. I ran mailing lists with over 100k total subscribers on an old Cyrix MIII based Linux box that had no problem keeping up with the load. If your users are using web-based email on your system, like hotmail or yahoo, then the number of users you'll be able to support will be significantly less.

As such, your i/o throughput capability (or lack thereof) may be the bottleneck. To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

I run an ISP and was using a PIII 200 MHz machine with 512 Meg Ram and supporting around 4000 active email accounts. It also handled outgoing mail, our admin functions, name service, YP master and some other low usage functions. I recently upgraded to a newer machine because it was available an had more disk space. With the old machine, I only say idle times under 90% when a user had their POP3 client set to not delete mail from the server and their mailbox grew to 100 MB or so. Then the POP3 server has to do a lot of I/O to get to the new messages. The issue is not so much the disk space as the time it takes to wade through all the old stuff. I try to convince users to correct their configurations. To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

I ran mailing lists with over 100k total subscribers on an old Cyrix MIII based Linux box that had no problem keeping up with the load. just to add to this, i've even heard of people running *bsd on a 486, and still being able to handle hundreds of users. in particular, i read about a firewall box running openbsd awhile back that received hundreds of hack attempts over a week-long period, and never skipped a beat. the same appears to be true for mail servers, too. - erk To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
