I am trying to stop the ever increasing flow of https://en.wikipedia.org/wiki/Email_spam#Related_vocabulary" rel="nofollow - Bacn , all these newsletters, discounts and social mail is a bit much.

I can stop a lot of it, but some I have not figured out how to stop as the message looks to legit.

Is there any way to filter on the HELO-Domain?

I see in the headers an entry like this:

X-SF-HELO-Domain: bmmpl3204.jpx1.emssnow.jp

The domain emssnow.jp is a Bacn sender, looks like http://www.bbc.com/news/technology-21830739" rel="nofollow - Bacn was identified several years back as being a major problem but I'm just getting around to attacking it more aggressively now.

Adding the ability to filter on the HELO domain would be a big help in the fight against the Bacn.
