Is there any way to add a static host entry to a C300 ESA?
I could not find anything like this in the GUI/CLI.
Every mail that goes from our internal mail gateways out through the C300s gets tagged with a Received header like this:
Received: from unknown (HELO mail1.ourdomain.com) ([x.x.x.x])
by mx1.ourdomain.com with ESMTP; 09 Dec 2009 01:53:21 +0100
which somewhat annoys me...
How can I make the reverse lookup match the HELO hostname?
I have this problem too.
