Hi
This is the same PID, look

2015-10-10 13:27:20 [26891] no IP address found for host smarthost.win.pl
(during SMTP connection from mx2.wp.pl [212.77.101.7])
2015-10-10 13:27:20 [26891] 1ZksJ6-0006zj-PI DKIM: d=wp.pl s=1024a
c=relaxed/relaxed a=rsa-sha256 t=1444476439 [verification succeeded] 2

Exim get such names from:
hosts - clear not info smarthost.win.pl
dns - clear not info smarthost.win.pl
all files in system is clear no find smarthost.win.pl

root@tax-net:~# nslookup
> set type=any
> smarthost.win.pl

Server:         85.11.67.250
Address:        85.11.67.250#53


** server can't find smarthost.win.pl: NXDOMAIN
i check any dns in resolv.conf - clear no such domain smarthost.win.pl

Regards
