i can't get it to work properly without exiscan-acl. if i invoke SA like
this:

sa_spamcheck:
driver = pipe
command = /usr/local/sbin/exim -oMr spam-scanned -bS
use_bsmtp = true
transport_filter = /usr/local/bin/spamc -u ${local_part} -U /var/run/spamd/sock
[...]

settings like envelope sender and ACL variables are overwritten. i.e.
the spamcheck transport is run after /etc/aliases redirect and
envelope-to is lost.

if i try the other way, without using BSMTP, just having SA in
transport_filter, if SA times out, procmail receives an empty mail, with
the only line being `From weirdo@??? [...]'. perhaps it is
sent even before SA is invoked.

i have no idea what to do about it. any hints?
