More false positives in junk mail lately - reset needed?
Question asked by Neal Culiner - November 6, 2015 at 8:38 AM

Hello,
 
I'm using SM 14.4.5784 Enterprise and recently I'm seeing a rise in false positives to where we have to watch our junk e-mail folder daily.  I have my filters set up per Bruce (I think that's his name??) and also use the message sniffer add-on, all has been working great.  Is SM "learning" or does it just use the filters / systems as is?  Is there something to reset or clear to resolve something like this?  Nothing has changed but the SM software and I'm concerned with the higher false positives I'm seeing.

Make certain you are on SmarterMail 14.4.5793.28950 - it's a special build and on the SmarterMail pages in the forums.  You'll need that to handle SPF, DKIM and DMARC exceptions which were causing false positives and were fixed.

 

In my experience, use nothing except the SmarterMail antispam, setup per my document.

Do not allow users to override spam settings.  Enforce Greylisting, and shut down all other antispam.

I will have it updated, to reflect additional spam from new domains, next week.

It will clean up a couple of issues with deleting all contacts, when you only want to delete one or two. If you can search for it, there will be an explanation with the original link.
