I get lots of spam from particular mailing services like Constant Contact and Mailchimp. 100% always spam from these services. Is there a way to block messages received through these services? I can see the domains in the header of the email but I don't see an option to block messages based on info in the header.

good luck

i think you would want to start with:

if header :matches "from" "somedomain" { discard; }

but i am just spitballing.

EDIT: i think there is a "reject" as well.

This is the basic filter. No idea about sieve filters.

Using a browser

Left side scroll down to "labels" and hit the cog.

Again on the left hit "filters".

Add filter, name the filter, hit next.

You can select subject, sender and 2 other options, add something to the box (perhaps the email you found in the header), hit next,

Now, decide where you want the email to go.
