Using SUSE 10.1 and KMail (by way of Kontact). New install (yesterday). Plus I'm a full newbie!

I have all email accounts set-up pretty much the same, including leaving messages on the server for 30 days.

Two of the accounts, though, are continuing to send the same message as if it is new. I have received the same 6 messages at least 10 times today. They are coming in with the same date/time, also.

Any idea what I'm doing wrong?

Much thanks,
David
