Using GW6 as POP3 Server - Some OL clients get multiple copies of msgs.

[bullwinkle]

My client is using GW6.5 as the local POP3 post office. Some of the
outlook clients (not all) are getting multiple copies of the same
message.
OL client (no express versions) ---
Network connection is std. tcp/ip (dhcp) POP3 server is static IP.
Leave copy is off
server querry time has been increase to 3 min
rules are turned off
single account config per user
std. user setup

Not all of the emails are multiplying. Kind of random which ones will.
Some internal some external. No real pattern has developed.
I'm open for suggestions... -jb
