Gilles,
Thank you for the time and energy you have spent on this. I appreciate
it.

Sorry but on a second thought, this is wrong for several reasons.
The main one is that aliases transforms recipient addresses BEFORE they are
matched
to a local user, so imagine you have something like:
OK, that answers my original, fundamental question: why aren't there
wildcards / catchalls in aliases. Now I know. Thanks!
If I were you, I'd try to fit my use-case in virtual rather than aliases as
this is
the mechanism intended for what you're trying to do. I had a look at Postfix
and if
I'm not mistaken they also have catchall part of virtual rather than aliases,
which
would likely be for the same reasons.
OK.
I worked up an alternative ... I actually only have four aliases so I
hardcoded them into the conf file like this:
# plain old unix usernames
action "users" mbox
# aliases
action "abuse" mbox virtual { "ab...@domain.com" = postmaster }
action "reminders" mbox virtual { "remind...@domain.com" = username }
# catchall
action "catchall" mbox virtual { "@domain.com" = username }
# explicit match rule for every unix user - all use the "users" action
match from any for any rcpt-to "u...@domain.com" action "users"
match from any for any rcpt-to "us...@domain.com" action "users"
match from any for any rcpt-to "us...@domain.com" action "users"
# Next come the aliases
match from any for any rcpt-to "ab...@domain.com" action "abuse"
match from any for any rcpt-to "remind...@domain.com" action "reminders"
# Last is the catchall
match from any for domain "domain.com" action "catchall"
This is weird and ugly but I am pleased with the actual result - are there
any dangers or pitfalls here that I am not noticing ?
Hope the example above helps someone in the future. If future readers
wonder how I handle multiple recipients for a single alias, I just cc: the
second or third recipient in .procmailrc ... so the normal alias syntax
of:
user joe,billy,bob
... is not actually possible ... I have to achieve that with procmail.
Thanks!
P.S. YES, I did indeed waste two hours on that thing where the rule is
written:
match from any rcpt-to "gil...@poolp.org" action "out"
... but it should be:
match from any for any rcpt-to "gil...@poolp.org" action "out"
