Thanks very much Brian.  I did as you suggested and people receiving my e-mail are able to reply automatically. 

I'm not sure what went wrong, or how it got fixed, but all is good!

Hi, I'm using v. 4.61 (Win32).  Everything was working great until yesterday.  I'm switching to another IPS and wanted to make the e-mail address there the default address, so made changes yesterday, and obviously screwed up something.

My e-mail address should be formatted as:  [myname]@shaw.ca.

But the "Send Reply To:" has this as:  [myname].shaw.ca@prod.shaw.ca

I searched and found another post on this topic.  The advice was to go to Tools/Options/outgoing mail/sending mail and then type in the correct address in the box labelled "Default "reply-to" address.

I did that.  It now reads [myname]@shaw.ca.

But that didn't fix the problem, which continued.

 Finally, I closed down the program, and then ran it again.  The box under Default "reply-to" address still reads:  [myname]@shaw.ca.

Now "Send Reply To:" is correct:  [myname].shaw.ca@prod.shaw.ca

 But when I hit reply, nothing is inserted in the "To:" field of the new message.

Any suggestions very welcome!  Thanks, Tom

This makes sense if you sent the message to yourself.  Pegasus Mail excludes your address in replies.  Do you have a gmail or yahoo account that you could send a test message to?  If not, use someone you know to send a test message to and test a reply.
