I agree, especially if it is setting between Pegasus Mail and the POP3 host.

Yes, no and maybe. In this case if you are losing mail that has been delivered to you POP3 mailbox then something is causing this message to not be received in the mailbox. FWIW, what spam filter are you using?
> ISP now suggesting that my email client is misreading the headers from the messages.
That one though I doubt, however the spam program you are using may be doing that.

Turn on session logging in Tools | Internet options | General and then check the session log. I would make sure that there is a message from the problem address before I started the download. One way to do that is to use File | Selective mail download to see what is on the POP3 host.
