I got annoyed by mailchimp emails sending newsletter and promos to my user and decided to block it using regex. screenshot.png

but it didn't work.
can anybody tell me how can I block mailchimp from sending us emails?
 
try this 2

Code:
(\W|^)[\w.+\-]{0,50}@[\w.+\-]{0,50}rsgsv\.net(\W|$)
(\W|^)[\w.+\-]{0,50}@[\w.+\-]{0,50}mcsv\.net(\W|$)

the addresses in the mail.log (and the tracker) usually refer to the envelope-from (smtp MAIL FROM) address - you can match these with a who object

a match field object for 'from' matches the header from address.

I hope this explains it!

I also added the domain "rsgsv.net" in who address and add to blocklist mail filter but still not catching it
