Agreed. The point being that those other options _are_ simplistic.

Well, I'm not going to write the config tool right now (or probably ever - I
never liked procmail - though I was working on one for maildrop), but start
at the beginning - sooner or later every recipe has to deliver mail to a
file, pipe or program, or to another user. It's simple to check that the
file/pipe/program exists. Validating an email address is harder - do you
simply check that the format is good, or actually test SMTP? Neither one
is impossible, though. Now, I can conceive of a situation where I might
actually forward to an invalid SMTP address intentionally (expecting the
address to be created shortly) but then it's a matter of what procmail
would do with such an address when actually running - if procmail will
retry, it's just a warning, if procmail would drop it, it's an error.

The "If A then B" conditions. In your example, procmail already checks
those, so why can't a config tool for procmailrc do the same?
