Additional spam filters — Gmail
I would ideally like to find a way where email bounces (or gets back to sender with a link) unless he is in my contacts list — well, if you’re not in my contact list the chance is very little that I have to talk to you, really.
What can we do:
Filter the word “Unsubscribe” :)
For me — that uses subfilters — it is to: (-drhus@drhus.com OR -husam.abboud@drhus.com) Unsubscribe
