Running Smartermail Enterprise 12.0.5178 on Windows 2008 32bit
We have the ReverseDNS spam check set up to return a score of 10 if it fails. However, it doesn't appear to be ever failing.
As an example see the following (truncated) headers from an email:
Return-Path: <xxxx@xxxx.eu>
Received: from 00148bbc.xxxxx.eu (UnknownHost [nnn.nnn.nnn.nnn]) by smartermail with SMTP;
Sat, 22 Mar 2014 01:03:04 +0000

X-SmarterMail-Spam: SPF_Pass, Bayesian Filtering, DK_None, DKIM_None
X-SmarterMail-TotalSpamWeight: 3
From the logs:
Spam check results: [_SPF: Pass], [BARRACUDA - BRBL: passed], [CBL - ABUSE SEAT - DO NOT CHECK OUTGOING: passed], [HOSTKARMA - BLACKLIST: passed], [HOSTKARMA - BROWNLIST: passed], [HOSTKARMA - YELLOWLIST: passed], [SORBS - ABUSE: passed], [SORBS - DYNAMIC IP: passed], [SORBS - PROXY: passed], [SORBS - SMTP: passed], [SORBS - SOCKS: passed], [SPAMHAUS - CBL: passed], [SPAMHAUS - CSS: passed], [SPAMHAUS - PBL: passed], [SPAMHAUS - PBL2: passed], [SPAMHAUS - SBL: passed], [UCEPROTECT LEVEL 1: passed], [UCEPROTECT LEVEL 2: passed], [UCEPROTECT LEVEL 3: passed], [VIRUS RBL - MSRBL: passed], [_REVERSEDNSLOOKUP: passed], [_BAYESIANFILTERING: failed], [_DK: None], [_DKIM: None], [HOSTKARMA - WHITELIST: passed], [SURBL - ABUSE BUSTER: passed], [SURBL - JWSPAMSPY: passed], [SURBL - MALWARE: passed], [SURBL - PHISHING: passed], [SURBL - SPAMASSASSIN: passed], [SURBL - SPAMCOP: passed], [URIBL - BLACK: passed], [URIBL - GREY: passed], [URIBL - MULTI: passed], [URIBL - RED: passed]
When a I do a manual PTR lookup against the two dns servers in the Smartermail setup it times out, as it does when I try a number of other servers.
So this should have resulted in a [_REVERSEDNSLOOKUP: failed]
Any ideas why this is not occurring?
TIA
