Hi, me again trying to bend Exim in silly ways :)
I'd like to customise the reject I send when recipients don't verify to be
more rude to clients listed in $my_preferred_rbl_lists. Basically I'd like
instead of saying "that address doesn't work" to say "I don't want any
mail from you". I guess it's cosmetic, but given that I've already done
the lookup it's not going to cost me anything extra. Valid recipients will
receive the mail tagged with an "X-RBL-Warning" header added by one of my
ACLs.
So I tried this as my last "real" router (I have one which should only be
run when explicitly called from a different one after this..).
spam_baduser_reject:
driver = redirect
retry_use_local_part
allow_fail
data = :fail: \
${if def:h_x-rbl-warning:{$h_x-rbl-warning: or mail abuse@REAL_DOMAIN} \
{unrouteable address}}
..but of course, def:h_x-rbl-warning: is never true at this stage :-/
So, is there a way of doing this using a router, or do I have to do dark
things with my already-fairly-complicated ACLs? If the latter, is it
something like
deny message = "sod off Mr ORDB-listed host"
hosts = +rbl_hosts
dnslists = relays.ordb.org
!verify = recipient
..?
