Tips for speeding up pop server?

[kcdworks]

A few of my users (on a server with a very small population) are complaining of slow auth times on the mail server. Anyone have any tips to speed this up? I've never noticed my own mail on this server running slow, but with multiple users reporting it I have to see what I can do.

We've been experiencing about 20-30 sec sleep time before POP/SMTP authorization in the last couple of days. Very wierd since we haven't changed anything..

Check resolv.conf - could be that your nameserver info got wiped.

That was it exactly! Thanks for the help!

Simply make sure that the nameservers listed in that file are valid and working.

can u edit it as a root via SSH?

That's what I did ... but don't forget to back it up first!!!

Yep - using pico, vi, whatever, edit /etc/resolv.conf and check whether you see your nameservers listed, or 127.0.0.1

If you don't see your nameservers listed, you need to add them...

domain domain.com
search domain.com
nameserver nameserver 1 IP
nameserver nameserver 2 IP

but the problem is that I cannot edit it via SSH logged in with root.. it said permission denied......
