At work, I am using Red Hat Linux 7.3 as a mail server and Red Hat 
8.0 as
one of the workstations, and I am finding that the imap response time is
woefully slow.

I will click on "Get Mail" on the workstation and at times it will take
over a minute to return a response from my mailbox. We have a number of
POP3 users too and by comparison, POP3 is very fast. For email 
clients, I
have tried Mozilla Mail, Evolution, Sylpheed and Kmail and it is the 
same
for all of them. Sometimes the mail client actually times out and says
that it has lost contact with the mail server, as it has taken so long.


Try to install the following iptables rule on the machine you run the
imap client on:
  iptables -A INPUT -p tcp -i IFACE -d IP --dport 113 -j REJECT
   (replace IFACE with eth0, eth1 .... and IP with the ip address)
Does this solve your problem?

Hi Friedrich.

Thanks for your reply. I am not using a firewall between my workstation 
and the mail server, so  I don't think that Iptables will be relevent, 
will it?

BTW, I am now using RH9 on the workstation, and it is still the same.
