Default SPF check errors
Hi,

we are evaluating the Astaro Mail Gateway behind a ASG. The AMG is receiving all the email through a NAT rule on the ASG passing smtp ports to AMG. The ASG is still relaying all the mail to outside.
No problem here.
The problem is that some incoming mail is getting rejected by SPF with error:
"(our ext IP) is not allowed to send mail from (some ext domain)"

witch in fact is true but it doesn't make sense.

Than I notice that in "Mail Manager" - "SMTP Log" all messages seem to come from our ext. IP.
This cant be right.

I'm out of ideas.

Thanks in advance.

Problem solved.

The "FULL NAT" rule was the culprit.
We modified it to DNAT because we already have a Masquerade rule in place and is now OK.
