Try a new, more in depth approach with Spam filters that a partial match of Sender email account can be used to clear continuous SPAM emails
If Spam emails show User is 25549446@____, and you continue to get Spam from the same Sender of 25549446 but from various different domains (in my case over 1000 in just a few weeks!) then there should be a way to filter "25549446" as a partial match rather than having to filter each and every SPAM email. This would clear all SPAM emails coming from such Senders with just 1 of the 500 possible entries. If there is a set up for this already please explain it, Thanks!

Same would go for SPAM emails showing a reoccurring partial of any SPAM email such as email@example.com where the "@1217883.77" is repeated with various suffixes of different domains as well as different Users. Over the last 6wks I have received well over thousands of these SPAM emails too!
