I was thinking of adding a second line to the antispam reject

550-5.7.1 The existing reject message
550 5.7.1 Please see http://foo.example.com/ for support.
Nice.
One catch-all banner is infinitely better than nothing, and it's a good
first step. If, in ANOTHER four months, somebody ELSE requests
per-error customization, THEN maybe the foundation will have already
been put in place, so it won't be as dramatic a change.
I don't think that it makes sense to do fine-grained customizations
for each possible reject reason
Counter argument: By making it configurable (ergo, more flexible) then
that decision is left up to each site's administrator. *Shrug*
In my case, I just want to help people help themselves. I desperately
need for folks to understand that this particular problem isn't on our
end, rather, they need to work with their IT department and/or ISP to
either straighten out their forward <=> reverse DNS mappings, or simply
relay through their upstream MSA or Authenticated SMTP server, if
available (preferred).
I don't, yet, have multiple "example.com/error-one.html" and
"error-two.html" landing pages, but the forward-thinking software
engineer in me thinks, "Maybe I, or somebody else, WILL want that
someday..." If the more prudent approach is to wait and cross jump that
bridge when we come to it, that's fine, too. I don't know enough about
Postfix's internals to appreciate the level of effort involved (ie,
whether it's easier/harder to go: Zero -> One -> Many, or Zero -> Many.)
I appreciate your-all's willingness to explore the issue, though! Even
if we only end up with Wietse's general-purpose error banner, I still
think we've made progress.
PS - Here's an updated patch

manpage/documentation updates as well:
