Thanks for the update. I'm working on implementing this now,
however, I'm a bit confused with the postscreen_dnsbl_reply_map
option.
Why? It's just for mapping RBL names. Unless you have a paid
subscription with spamhaus.org, you don't need it.

Hi all,
id like to modify the message postfix sends to the server when it
rejects an email in one of the checks performed.
For example,
450 Helo command rejected: Host not found; http://readhereforemore.info
that administrators which have no clue about email systems have a bit

Mind has check_sender_mx_access so and logs appropriate messages if the MX
results are unacceptable.

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 PTR in place.. the email was rejected..
That's not an MX problem, but a missing PTR. Postfix can check for
this using:
Ralf..
A MX lookup is performed to check if the sender domain exists; it can
be activated using:
reject_unknown_sender_domain
is what I was looking for..
Thank you ..

If these hosts are using you as their smarthost, simply whitelist their
