Does Postfix do an MX lookup on "inbound mail" as part of

Mind has "check_sender_mx_access" so and logs appropriate messages if the MX

What are you trying to achieve, as it seems unlikely to me that you have a
purely academic interest in the mix of DNS requests generated.
It was a question that came up in a discussion..
I have had issues in the past when delivering email and I did not have

Thx for the response..
