check your setting of 'enhancedOriginIPDetect'

2015-08-20
fixed in assp 2.4.6 build 15232: 
....
changed:

'enhancedOriginIPDetect','Do an Enhanced Origin IP Address Detection in 
the Mail Header',
'0:disabled|1:all|2:all but most origin'
....
Default setting is 'all but most origin', which ignores the first public 
IP address, that was involved 
in the mail transport (possibly a user device).'

Betreff:        [Assp-test] query DNSBL by which IP?



Hi,
v2.4.5(15272)

(...)
Received: from mail.gbn.pl ([93.179.224.25] helo=mail.gbn.pl) by
     assp.ourdomain.com with SMTP (2.4.5); 16 Oct 2015 13:56:07 +0300
Received: from komputer1 (dtt185.neoplus.adsl.tpnet.pl [83.22.1.185])
     by mail.gbn.pl (Postfix) with ESMTP id A2C2E40BBC4
     for <u...@ourdomain.com>; Fri, 16 Oct 2015 12:24:48 +0200 (CEST)
(...)

as a result :
X-Assp-DNSBL: failed, 83.22.1.185 listed in 
(safe.dnsbl.sorbs.net<-127.0.0.10; )

the guy obviously sent the mail thru a dsl connection (at home or SOHO 
or wherever) which is listed in SORBS blockwise. that's ok so far.

OTOH mail is relayed thru gbn.pl, which is an ISP, certainly following 
an authorisation via SSL/TLS. IMO that's a very legit behaviour (and 
mail was legit indeed).

however it ended up with DNSBL block due to initial IP nr.
is this so by design or..?
