Put '@domain.com: x500' into aliases, then makealiases.
Put '| /usr/local/sbin/mail500 "$EXT"' into aliasdir/.courier-x500-default
Read http://www.courier-mta.org/makealiases.html
Read http://www.courier-mta.org/dot-courier.html
Mind the double-quotes around the environment variable in the .courier file, unless you want your server to be hacked.
Hi Sam,
Thanks for the suggestion, never thought the aliasdir stuff could handle this sort of thing.
Finally had a chance to try it out and got some strangeness:
isolar:1:81 [/opt/courier/etc/aliasdir] # cat .courier-x500-default
'|/usr/local/sbin/mail500 -f "$SENDER" -h "$HOST" -m [EMAIL PROTECTED] "$RECIPIENT"'
isolar:1:82 [/opt/courier/etc/aliasdir] # tail -1 ../aliases/system @isolar.DynDNS.ORG: x500
I got a bunch of error messages that made it look like it failed:

And, I got a "NOTICE: mail delivery status." error e-mail But then, bizarrely, right after that in the logs is this:
Nov 19 21:12:12 isolar courierd: [ID 702911 mail.info] started,id=0012FC94.419ED22C.00005AFE,from=<[EMAIL PROTECTED]>,mod ule=esmtp,host=isolar.DynDNS.ORG,addr=<[EMAIL PROTECTED]>

Nov 19 21:12:12 isolar courierd: [ID 702911 mail.info] completed,id=0012FC92.419ED22C.00005AFB
and sure enough, I checked my INBOX and the e-mail is there! I thought surely the errors above (no idea why they were all doubled, either) meant that attempted delivery didn't work - unless it "fell through" and was forwarded out by something else (esmtpd?) but if that was the case, it wouldn't have known to connect to the other mailhost and change the "for <[EMAIL PROTECTED]>" recipient. In the Received headers I see:

So, my first question was going to be, "What did I do wrong to get all those elements of the .courier-x500-default file parsed as individual recipients - is it a quoting issue?", but now I have to add to that "... and how did it apparently work anyway?"!
