I'm running sendmail under RedHat 7.1. I can send e-mail out but I get an unknown user error when I try to e-mail myself from hotmail. My server is seeing the mail because it shows up on my logs and I also get a message in my "root" mailbox. I have an account set up as a regular user and I have a virt user table set up. Can anybody tell me what I might be over looking?
