Hi all. This is not a postfix-specific question, but rather a generic one, but I hope I can get the answer I am searching for here.
I run a third part SMTP filtering program in which I have "EHLO/HELO Must Resolve" turned on. I am amazed at the number of exceptions I have to put into my configuration to accept email from domains affected by this. Is this normal practice, or, according to RFCs, is the FQDN _REQUIRED_ to be present in the EHLO/HELO verbage during an SMTP session?
