After putting in my pop server settings of my pop account, I try to send a message. I keep getting this error message. This user doesn't have a yahoo.co.uk account (email@example.com)  - mta1038.mail.ukl.yahoo.com The servers I use doesn't have anything to do with Yahoo or even with the uk and I'm not sending the message to anyone with a yahoo account. I don't unsderstand what is going on. Anyone else run into this?
