Error 550 is a permanent fatal error. It means the email will never go
through.
Error 5.7.1 is a permissions problem:
Permissions problem. For some reason the sender is not allowed to email
this account. Perhaps an anonymous user is trying to send mail to a
distribution list.
Check SMTP Virtual Server Access Tab. Try checking this box: Allow
computers which successfully authenticate to relay
User may have a manually created email address that does not match a System
Policy.
