This is the Exchange explanation for 5.7.1:
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.

Hi Mr. Orland
Thanks for your answer, the tab it´s selected, sending internal mail from
remote users works, but to external mail not.
