That is a .courier-default in aliasdir. I configure it to dynamically call a
script, e.g. `|| /etc/courier/aliasdir/rcptfilter.sh' or whatever. The script
can either output the real destination address or refuse the mail, thereby
causing a bounce to be generated.

This can be done better using the same script called on delivery. When called as
a whitelist filter, the script can decide for an on-line refusal (SMTP error)
rather than a bounce. I posted on this subject on Fri, 27 Oct 2006 20:53:29 +0200, see e.g.
