Rather than 'deny' I prefer to use 'drop' to forcably close the SMTP
connection when a spam message has been detected, and I delay that response
for 15 to try to slow down the sender slightly. I'm doing some mail relaying
for some domains in which the admin on the other side wants the spam to be
accepted and then discarded rather than rejected, so the combination is the
following:
acl_check_recpt:
warn
domains = !+spamdiscard_domains
set acl_m_denyspam = yes
warn
domains = +spamdiscard_domains
set acl_m_denyspam = no
acl_check_data:
drop
hosts = !+relay_from_hosts
condition = ${if eq{$acl_m_denyspam}{yes} {yes}{no}}
!senders = postmaster@*
message = Spam message detected; message rejected.\n\
If you think this is wrong, get in touch with postmaster.
condition = ${if match{$recipients}{postmaster}{no}{yes}}
condition = ${if >{$spam_score_int}{50}{1}{0}}
log_message = msg rejected due to spam score of $spam_score
delay = 15s
discard
hosts = !+relay_from_hosts
condition = ${if eq{$acl_m_denyspam}{no} {yes}{no}}
!senders = postmaster@*
message = Spam message detected; message discarded.\n\
If you think this is wrong, get in touch with postmaster.
condition = ${if match{$recipients}{postmaster}{no}{yes}}
condition = ${if >{$spam_score_int}{50}{1}{0}}
log_message = msg discarded due to spam score of $spam_score
