Can someone that's running vpopmail with 600+ users please
recommend a better way of running the pop3 service? My
current setup is running it out of tcpserver, and my run
script(for svscan) is at the end of this message.
The problem that I'm having with this setup, is many many
people are getting a fairly decent amount of lag when first
connecting to the server.. at least 20 seconds.. but many
people are also NOT having any lag at all. I've managed to
connect to the server with over 200 simultaneous sessions,
and I still had room for more. Another problem is that some
of our customers' email clients are timing out during
authorization (but they do manage to connect). None of this
can be internet lag, as it's all local network traffic. I've
noticed at most 8 concurrent pop3 sessions going. I'm
completely lost as to where to go with this now. I really
hate the idea of having to go back to NT for email, but this
may be the only option, as too many people are calling up to
complain.
In case anyone is interested, the server is FreeBSD
4.1.1-STABLE. It's services include: smtp, pop3, and http for
sqwebmail. The box is a Pentium I - 200MMX, with 64MB RAM,
160MB swap, a 20GB drive, and a Netgear FA310TX NIC.
Here's the contents of the pop3 run script:
#!/bin/sh
exec /usr/local/bin/softlimit -m 1000000 \
/usr/local/bin/tcpserver -H -D -c 150 -v \
-u vpopmail -g vchkpw 0 pop3 /var/qmail/bin/qmail-popup \
mail.ourdomain.net /usr/local/vpopmail/bin/vchkpw \
/var/qmail/bin/qmail-pop3d Maildir 2>&1
