Thanks for the hint Todd.
I've replaced it with:
smtp_dns_support_level = disabled
and it's still working as expected.

My intention was to send emails to a single domain with any other email
traffic being disabled.
In order to achieve this I considered smart host, dnsmasq and even bind9.
The 3-liner solution that I've found seems the simplest, least intrusive
and appears to be working fine.

I assume that you are not trying to achieve "smart host" configuration
for sending mail.
Perhaps you can run a dedicated dnsmasq instance with no upstream DNS
servers. Option that might help

Routing Internet email in the absence of functioning D
I get:
0A032940922 657 Mon Jul 15 14:40:01 user1@mymachine
(Host or domain name not found. Name service error for name=example.com
type=MX: Host not found, try again)
Any SMTP client which does not fall back to the A record when no MX
records exists is fundamentally broken.

I didn’t test it but no MX was found then local MTA should try A record
for delivery.
As a proof that safe-mail.net has no mx but A record only.

I want to achieve the first objective and the values are static.
I just hoped there is a one liner hack (like A records in /etc/hosts) to
achieve this vs reconfiguring my MTA.

Given you want to send mail to foo.com whose mx record is mail.foo.com
whose IP is 1.2.3.4
Then write this entry in hosts file:
1.2.3.4 foo.com
Which should work for sending mail.

I don't think I can add MX to /etc/hosts which only works for A records.
I'm after a similarly simple, "one liner" solution.
