[IMail Forum] VALHELO spam test

[Jim Comerford]

Title: Message

we have Imail marking X-IMAIL-SPAM headers on e-mail.  We have some rules setup to bounce based on certain tests.  Others we pass thru and allow users to move the messages in outlook via rules - the VALHELO is one of those we dont automatically block.   One of these tests X-IMAIL-SPAM-VALHELO seems to fail sometime and not others.  This failure happens both with mail sent within this IMAIL server, and from some users outside this system - but in both cases they seem to work sometimes and not others.  I'd like to debug this behavior, but am unfamiliar with what the HELO test actually does.  Any resources that would help like what to look for in DNS and/or how to verify it with a telnet session would be appreciated.    Thanks, Jim
