Like someone else mentioned it could be a duplicate IP address
problem. Run a sniffer, do a ping and see how may replies come
back from the arp. Also, I've run into problems before with
DNS servers gone flaky causing similar problems. Try putting a
host file in the mail server and Unix boxes with entries for
the client machine your trying to connect from, it may be failing
on reverse lookups.

Subject: ip routing
Hello,
Last week we have encountered a problme with slow e-mail access on one
of the subnets on our network. We've done extensive troubleshooting.
We've repalced the router, token ring switch, NIC on the e-mail server.
Then we found out that if we change the ip address of that lan
everything works fine. So the problem is either with an IP address or
routing that particular ip address. Another thing is that from that
subnet we were not able to telnet to some of the Unix machines that we
have on the same subnet as e-mail server. I do not know if it is related
or not.
Here is the topology.
TR-LAN---3600-----5505 with RSM-----3548---e-mai ser.
Thanks
