(You knew this was coming...)

Deliver 2.0, patchlevel 9 (which should be out today) supports bounces
with user-specified error messages.

Delivery files can output a string of the form "user?error message",
and the resulting error report will include the given error message.
So to do what you request:

>What I would like to do is to bounce mail for such users back to the sender,
>with a useful message, like "Account expired."

Create a post-user delivery file that looks like this:

	for u
	do
	    if grep "^${u}$" /usr/lib/mail/expired >/dev/null
	    then
		echo "$u?Account expired."
	    else
		echo "$u"
	    fi
	done

Then create the file "/usr/lib/mail/expired" with a list of expired
accounts, one per line.
