Thomas:

 Thanks for your quick response.  I think I figured out the problem on my own.  By examining CC and BCC as well as To and From, the POP3 Client tried to send the emails with CC's to other company users to the recipient as well as to all of the folks on the CC list, with the result that some users got the same message as many as six times.  I removed the CC and BCC from the Headers box and now have POP3 Client examining only To and From.  So far, no problems.  

In our setup, we have the POP3 Client picking up all incoming email from one common domain mailbox, the redirecting it through the Mercury Core Process and to the SMTP Client (relay version) to send it to the personal email accounts of the various users.

If I see any strange duplicates popping up, I'll get some more information and post it here.

Many thanks!

Ron

We have a system that sends "Trouble Ticket" emails to several users where all of the emails appear to be identical.  The POP3 Client allows the first one to go through and stops all of the subsequent copies.  I found a work-around that involves checking the "Check only in these headers" box of the Optional Special Header Processing section and put "To;From;Cc;BCC" in the Headers box.  That fixed stopping the duplicates, but now when a user sends an email cc'ed to multiple users, each user gets up to six copies of the same email.  How do I fix this?

This has to be something unique in the headers that defines the users address.  Show us a copy of the entire message, just paste it into a reply, and we'll be able to help you a lot more.
