When I send emails to outside recipients, they are
returned with the error message “550 User Unknown”
or “553 User Unknown.”
Check the email address of the recipient and verify it is typed
correctly.
From your Exchange or Netscape Messenger click
“Send/Receive” once and then attempt to resend the mail.
Some domain hosting services require that you log in using
POP3 (Receive) before sending email.
I can send mail but I cannot receive emails
Check and verify you have entered correct User Name and
Password. Go to Remote Admin/System/Users, click the user
who is not able to receive emails, “Verify ISP E-mail Acct”
and “Password” fields. Try reentering the User account and
Password.
