Eric,
I have found out more information.
It must be firewall related somewhere. The firewall is off (iptables) but I
still cannot get access.
However, I did notice that the CentOS firewall (in the GUI - Security and
Firewall settings), was set to "Enabled", even though the iptables service
was off. So I "Disabled" this setting, applied and restarted the box. Mail
on port 110 then started working.
After making sure this was appropriate, I then started iptables. Mail on
port 110 stopped working. I then stopped iptables, but port 110 still
refuses to work. If I change the incoming port to SSL (995), it works, so
port 110 is being blocked by something apart from iptables.
Do you know of other areas that CentOS 64bit keeps firewall type
information?
And thank you in advance for your support.
Cheers

I guess you'll need to set up recordio to see what's going on. Recordio
is a program that logs the details of a tcp session. Search the list for
directions on how to use it (you'll edit the run file). There might be a
wiki page for it, but I don't remember there being one.
If you're really stuck after that, you might consider trying out
dovecot's pop3 instead of qmail's. I really haven't heard of any
problems like this with qmail's pop3 though.
Are you sure the client is using the whole email address as the login
name, and not just the name before the @ ? That's a common mistake.
