When iredmail was installed earlier this year, it was filtering spam messages very effectively. lately there has been a gradual increase in spam that is not being filtered. On checking message  in iredmail pro portal I am noticing that many of the messages that are obviously spam are not scoring correctly.  many spam are getting a score of 2.9 or less.

I do not know where to start with working out how to stop this from happening and I am hoping you may be able to point me in the right direction.

Re: spam not being filtered.

*) Seems many spams came from same sender domain, you can blacklist the domain name.
*) Check the mail header to see why they have low score, then tune it based on the spamassassin rules.
