nslookup of client domain points to IP.
when I do nslookup of IP, it points to another host name.
(I do the hosting).
I don't know this result is taken from root DNS or just from cache of my
ISP. But email login is preety fast. The only thing that slowing down is
protocol initialization.

CMIIW, email client will do these steps while talking to POP3 server:
- Lookup for host IP
- Initialize protocol with port 110
- Send user name and pasword (login)
- etc...

All of them are preety fast, except when initializing protocol. Once it
initialized, sending username, check password, list command, download mail
are fast as usual.
It happens to FTP, telnet, DNS and SMTP. The only port which still fine is
80.

So, what's wrong with my RaQ3?
