It is a few days that a server working about 2 years, seems unable to deliver mail to some users. The error is quite always

Diagnostic-Code: smtp; 550 Administrative prohibition

Any hint in what could be the reason.

Keep in mind that this server is up and running more than one year and this problem started only few day ago.

HELP !!! smile

Attacched the full response email received to one of theese refused mails.

Tnx

Seems recipient server refused to accept your email. You'd better contact the mail server administrator to understand why it happened.
