Well since most of the Linux versions are mentioned, I will say that I have
this running on HPUX 11.11 with qmail/vpopmail/qmailadmin with no problems
other than the install of qmailadmin requiring modification of the qmailadmin.c
file from seteuid/setegid to setuid/setgid. It works well and currently handles
about 1 million emails a month.
likewise, my entire current business ( http://www.smileglobal.com ) is built around vpopmail/qmailadmin/vqadmin, and of course qmail/djbdns et al, and i run the entire thing on a tiny* farm of Sun SPARCs running solaris 9.
i'm happy as a clam.
oh yeah, running clamav and spamassassin too of course. ;^)
*Farm consists of:
1 sun Sparc 20 - dual 75Mhz CPUs - primary NS, primary MX
1 sun Sparc 20 - dual 75Mhz CPUs - secondary NS, secondary MX
1 sun Netra T1 - 360Mhz CPU - spamassassin/clamav proxy, tertiary NS
1 Ultra 2 - 200Mhz CPU - the vpopmail/qmailadmin/vqadmin multi-webmail IMAP POP kitchen-sink
(soon to be replaced with another Netra T1 440Mhz with D130 disk array)
(webserver for our customer facing website is a RAQ XTR)
I don't know what my mail volume is, actually. I don't keep the logs around for more than a few days. my primary MX shows 74K messages inbound to my customers from 2:30pm 31oct03 to now (8:20pm 03nov03), if that gives you a rough idea of inbound volume.
I love sun sparcs and solaris. been running them for a decade now. ridiculously reliable and easy to administer. i know lotsa folks dislike solaris. frankly, i don't get it. it's an extremely powerful OS.
