This message was not processed because it contains an invaild reci

[Jason]

I am using Outlook 2007 with pop3 mail fom XO.

I receive serveral emails a day from a sender. I get most but usually 1 or 2
give me this error.

"This message was not processed because it contains an invaild recipient"

Then the rest of the message is random characters. I have googled this but
have only seen a couple people report this same problem.

Also if I check the message on my pop3's webmail. It appears just fine.

Any ideas?
