We're running Smartermail 12.3
It looks like Smartermail is not identifying spam and I'm trying to get to the bottom of this.
For example, here are some details about one spam email:
email headers show:
X-SmarterMail-Spam: SPF_Pass, DK_None, DKIM_None
The delivery logs show:
[2016.09.20] 14:57:35  Spam check results: [BARRACUDA: passed], [CBL - ABUSE SEAT: passed], [SPAMCOP: passed], [SPAMHAUS - CBL: passed], [SPAMHAUS - CSS: passed], [SPAMHAUS - PBL: passed], [SPAMHAUS - PBL2: passed], [SPAMHAUS - SBL: passed], [SPAMHAUS - XBL2: passed], [_REVERSEDNSLOOKUP: passed], [_BAYESIANFILTERING: passed], [_SPF: Pass], [_DK: None], [_DKIM: None]
The IP address of the spammer is listed on MULTIPLE blacklists:
Checking 188.8.131.52 against 97 known blacklists...
Listed 9 times with 0 timeouts
Blacklist Reason TTL ResponseTime
LISTED ivmSIP 184.108.40.206 was listed
LISTED ivmSIP24 220.127.116.11 was listed
LISTED NoSolicitado 18.104.22.168 was listed
LISTED Protected Sky 22.214.171.124 was listed
LISTED RATS NoPtr 126.96.36.199 was listed
LISTED SORBS NEW 188.8.131.52 was listed
LISTED SORBS SPAM 184.108.40.206 was listed
LISTED SPAMCOP 220.127.116.11 was listed
LISTED Spamhaus ZEN 18.104.22.168 was listed Detail
In Smartermail, we have the following configured:
Spamhaus - CBL
Spamhaus - CSS
Spamhaus - PBL
Spamhaus - PBL2
Spamhaus - SBL
Spamhaus - XBL2
(each using hostname zen.spamhaus.org, and with a specific 127.0.0.x Required lookup value)
We also have other RBLs including SpamCop.
The spammer's IP was listed on Spamhaus Zen and on Spamcop.
The weight settings for the domain and email account are such that there should have been a weight of 20 given for each blacklisting yet the spam score was 0.
I'm looking for some guidance in tracking this down.
Why do the delivery logs show "passed" for everything, would it show failed if something was on a blacklist?
