Pflogsumm emails through amavisd and SA hitting BAYES_99

[Simon Wilson]

Hi all,

I have pflogsumm running log summaries on my postfix install, and  
sending to an address that resolves locally. All is on localhost,  
which is a newly installed CentOS7 server, amavisd-new 2.10.1 from EPEL.

The pflogsumm emails from root are triggering BAYES_99 as they go  
through amavisd-new and spamassassin, and are often ending up marked  
as spam.

What's the best way to ensure that those are not flagged as spam, or  
potentially to whitelist them somehow?

Thanks
Simon.
