This is getting seriously off-topic. Setting the DNS-based reject codes
to 5XX is recommended as soon as one is confortable that the settings
are correct. Persistent 4XX rejects that *don't* represent temporary
conditions are worse for the sender.

So either use "reject_unknown_sender_domain", ... with 5XX codes after
brief testing with 4XX codes (or soft_bounce=yes), or don't use them
at all.

Let's not drift into rec.talk.* territory. No off-topic followups please.

If my response solves your problem, the best way to thank me is to not
send an "it worked, thanks" follow-up. If you must respond, please put
"It worked, thanks" in the "Subject" so I can delete these quickly.
