Hello, There are a few changes we want to make to our outgoing email headers, including to the Received headers that our MTA adds. I know that some tools including SA have some tests that judge spamminess based on malformed Received headers, but I have not been able to find anywhere that describes a definitive valid syntax for that header.
In order to make our changes without doing something that will get us penalized for invalid Received headers, I'd like to ask for assistance as to its expected format, in general, or at least as far as SA is concerned. If I missed a wiki page about it, links would be appreciated. Thank you, Ori
