Last year I have gotten a Athlon MP 1900 with an IPC-Vortex Raid-5
and three IBM 146 GByte (U320/10000). I have tested it with
postgresql and with a smpt/pop3 Server.
I have made a stresstest by seting up 50 users and subscribed all to
more then 40 debian-* Mailinglist... Traffic enough !!!
The server has handled more then 220 Mails/second unfortunately I
was not able to test in the same time user accesses with pop.
OK, for you a little Bbit overkil like for me...
I think, I will handle only 500-800 Users with normal traffic which
mean, around 10-20 mails a day.
Traffic which can handled by a Duron 900MHz, 256 MB and a RAID-5
Array of 3 x IBM 18 GByte (U320/10000) on an IPC-Vortex.
My Dual-Athlon will be the central nfs-Server of my Cyber-Center/
Internet-Cafe in Strasbourg, where users have 100 MByte Diskspace,
Which can used for private files, ~/public_html, ~/mail and
ftpspace inside of ~/public_html. in plus it serves Webmail, pop3,
asmtp and suports 30-40 Workstations with nfs inside my Cyber-Center.
I have used Webmin but it does not what I need and now I use my
own php4 Scripts to manage the users...
I think, there is no problem with the traffic.
Oh yes, if I run public, I will use 4 + 1 Harddisk.
