Hello Davide To continue thread about crlf problem, here are some points that trouble me.
In a xmail server used as a gateway with NO filters at all, just mailproc.tab files that do relay to a av server (Symantec AV for SMTP Gateways) then the av server relay to the real server, the av server reject some mails for the following reasons (not virus related but 'rfc' related) : *********************************************** 550 Requested action not taken: NUL characters are not allowed. ----------------------------------------------- [<00>] XMail bounce: [EMAIL PROTECTED];Error=[550 Requested action not taken: NUL characters are not allowed.] [<01>] Error sending message [1100590915441.2252.msg] from [xxxxxxxx.xxx].

A bug in the av server software ? - Accept malformed SMTP 'MAIL FROM' email addresses ... (here @globalpac.com alone ...) Any idea about what can generate these errors (xmail, the av server, others ....)?
