Hello, I am using an acl in exiscan to reject spam at smtp time. Everything
works great most of the time, but occasionaly a message or two gets through
even though the header clearly shows that the message was scored as spam.
The only thing that appears to be common with these messages that get
through is that the message is addressed to an email address that forwards
to another local address (i.e., domains@??? is a forwarder to
steve@???). And, the messages in question appear to be addressed to
multiple recipients. Anyway, I am stumped. My exim acl works fine 90% of the
time, but it's just a few messages that get through... And you will see that
I'm dropping messages with a score of 7+ and the message that got through
was scored 15.8.
I'd appreciate some help. Thanks very much.
Steve

Here is my exim acl:
#!!# ACL that is used after the DATA command
check_message:
require verify = header_sender
# Reject messages with a SpamAssassin score >7
deny message = Rejected: Flagged as spam (score = $spam_score).
spam = nobody:true
condition = ${if >{$spam_score_int}{70}{1}{0}}
accept
