Bounces are never sent to more than one recipient.
drop message = Legitimate bounces are never sent to more than one recipient.
senders = : postmaster@*
condition = ${if >{$recipients_count}{0}{true}{false}}
Drop if more than 3 bad recipients.
drop message = REJECTED - Too many failed recipients - count = $rcpt_fail_count
log_message = REJECTED - Too many failed recipients - count = $rcpt_fail_count
condition = ${if > {${eval:$rcpt_fail_count}}{3}{yes}{no}}
condition = ${run{/etc/exim/scripts/log-file /var/spool/spam/host-spam.txt $sender_host_address}{yes}{yes}}
!verify = recipient/callout=2m,defer_ok,use_sender
Drop if any of the recipients mentioned is one which only ever receives spam (ideally, a spam "trap" address):
drop condition = ${lookup{$local_part@$domain}lsearch{/etc/exim/only-used-by-spammers} {yes}{no}}
logwrite = :main,reject: $sender_host_address - $local_part@$domain is only used by spammers
message = I don't think so
Suggestions for improving the
conditionwelcomed - e.g. maybe use match_address?
Drop if destination is myprotecteddomain.com or my2protecteddomain.com but source is not *myowndomain.com . It will log useful info in exim log and only give administration prohibited to the other mta. Great for domains you know sources. (generaly internal use domain) :
deny log_message = $sender_address is not permitted to send to myprotecteddomain.com my2protecteddomain.com
domains = myprotecteddomain.com : my2protecteddomain.com
! senders = *myowndomain.com
