Introspection of Header to block SPAM
I didn't see anything in TB's filtering/SPAM controls that would handle the following problem.
I recently started receiving a lot of spam, from different emails and/or domains. I've started digging into them and notice a common element in their source. They all show as coming from 'vpsnode12.webstudio.com' even thought the domain email and related IP address are different in each case
Received: from mail.toi-imc.com (vpsnode12.webstudio26.com [185.169.183.129]) by ns4.i-mecca.net (Postfix) with ESMTP id CE4144007A for <xxx@yyy.zzz>; Tue, 3 Sep 2019 18:09:01 -0400 (EDT)
So my question is, how can I create the eqivalent of a filter to make everything from 'vpsnode12.webstudio26.com' as SPAM since this is not exposed on the visibile message header or body.
Below is most of the whole source.
Thanks

Is this email continuing in the next 24 hours?
Hi Matt. Not sure what you mean by "continuing in the next 24 hours". I receive a lot of different SPAM emails but they keep changing the email address and/or domain name it's coming from.
My research has led me to believe that 'vpsnode12.webstudio26.com' is a known email relay for such nefarious acts. See https://sdf.org/?spammers.
So, to refine my query, if I am correct, how to flag a message as SPAM coming through a specific email relay.

In short you can not. However I just wondered what unsubscribing your email address from the mailing list would do.
Matt, I don't think I'd trust and 'unsubscribe' link from a SPAM email.
Update - I asked my domain/email provided ehosting.ca if they could don anything and they 'tweaked' there email server to block emails relayed through vpsnode12.webstudio26.com. Much reduced email now.
