I was wrong there; the alias expansion is printed in reordered fashion to the log; delivery is attempted in the specified order. > > forward(5) of a_user (that's the one tried first) > > |/usr/local/bin/procmail > > > > after that delivery to b_user is not attempted.

Therefore I see no real error condition there? The further testing was somewhat confusing: ordering of recipients in aliases(5) matters; also, which recipient got the ``|| exit 0'' or ``; exit 0'' in his/her forward(5). Up to two recipients, it seems, it needs to be the second rcpt; with more recipients I never saw a delivery to all of them, no matter who had the ``|| exit 0'' after the procmail call (or all of them). Tests with ``|/bin/cat > /dev/null'' in forward(5) made no difference.

Do you mean just having smtpd deliver to lots of recipients via aliases or something beyond that? Thanks, Marcus
