Hi
I have a ASL 4.021
The smtp-proxy is making relay (inbound) inside of external messages with internal user's and internal domain mail-from.
Mail Message example:
Received: from mailexterno.dominio.com (10.0.0.3 [10.0.0.3]) by mailinterno.dominio.com with SMTP (Microsoft Exchange Internet Mail Service Version 5.5.2653.13)

Received: from [200.214.190.1] (helo=c0134)
by mailexterno.dominio.com with smtp (Exim 4.22)

This way, externally, I have as sending messages to an internal user with another internal user's mail.
How can we correct the problem?
How don't I allow the entrance of messages with the mail-from same to my domain?
Thanks
