I received this email today. Has anyone ever seem anything like this or know where and why it is originating?
I am administrator of post domain integral.by and we have a little problems:
Your post server (kmgchemicals.com) should indicate the name of existent domain when messages delivery in command HELO (in accordance with document http://www.ietf.org/rfc/rfc2821.txt
, but your server sends "xxx-xxx-xxx and out domain" - this is incorrect value, and our post server refuse to accept messages from your post server (because this is a kind of additional SPAM protection).
Could you please correct this little inaccuracy in a setting of post server.
