Worked like a charm...Thank you!

Lately, we received a number of Spams that automatically generate a return receipt.

The Spam, as it comes in, is directed to the JUNK/Suspicious folder.

As we go through that folder to clean it up, each time we come across one of the offending messages, it generates a return receipt.

We then have to clean out the Que mail.

Any suggestions on how to stop that?

Thanks

I believe this is a "confirm reading" sent by the mail client instead of "return receipts" sent by the server.  Turn off the Tools | Options | Advanced | Accept requests to "confirm reading" 

This option only applies when you are not connected to a NetWare server. It determines whether Pegasus Mail should send automatic answers indicating that you have read a message when the "request confirmation of reading" flag is set in that message. If you uncheck it, Pegasus Mail will never send confirmation of reading. If you are running on a NetWare LAN this option will be greyed and you cannot change it - instead, alter the option in your Extended features preferences.
