DKIM for a multi-domain hosted filter

Postby Pentangle » Wed Oct 12, 2016 4:41 pm

Hi all,

We run a few instances of Mailcleaner in a cluster at our datacentre, filtering for about 300 domains.

Up until now, I've resisted adding DKIM due to the potential of false positives being generated by our other systems on the web that would send email to us and sometimes customers (e.g. monitoring emails from SNMP etc) as a lot of these don't get routed via our spam filter.

Am I missing a trick here and that I should be less worried about false positives? or are my worries founded and i'm likely to have a world of pain when turning on DKIM?
