I'm making no claims for optimal coding, but something like this works
for us (comment-out the "log_message"s when you're happy that it's
doing what you want):
Main configuration:
addresslist suckers = recipient@??? : etc.
(or reference the contents of an external file or db, as you wish)
RCPT ACL:
# acl_m4 will compute the spam acceptance level of this user,
# the value is needed only locally;
# 1 = default, 2 = spam suckers, at present
# acl_m5 will note the spam acceptance level of this run: it's
# needed to be retained throughout the message,
#
# undef = no recipient yet
# 1 = normal antispam; defer any suckers
# 2 = sucker recipients; defer any normals.
warn set acl_m4 = 1
warn recipients = +suckers
log_message = TEST: sucker because of recipient $local_part@$domain
set acl_m4 = 2
warn local_parts = postmaster : abuse
domains = +local_domains : +relay_domains
log_message = TEST: sucker because of local part $local_part
set acl_m4 = 2
warn condition = ${if def:acl_m5 {no}{yes}}
set acl_m5 = $acl_m4
# log_message = TEST: acl_m5 undefined, setting it to $acl_m4
defer condition = ${if eq{$received_protocol}{asmtp} {no}{yes}}
condition = ${if ={$acl_m4}{$acl_m5} {no}{yes}}
log_message = TEST: defer because user is $acl_m4 but run is $acl_m5
message = Deferred - please try this recipient again later
Of course you'll also need some tests which bypass your normal
spam-rating procedures depending on which kind of recipient run you're
dealing with: details depend on just how you've got that set up at the
moment, I guess. The above is only the mechanism for doing the
deferring. Is that OK?
