I'm getting a lot of spam in Thunderbird from senders with long and highly repetitive nonsense addresses? I think a filter for the sender's address "contains 150 wild card characters" would work but I've not found a way to do this. Does such a wild card character exist in the filter? Is there another way to do this?

Thanks

well you could try an address contains criteria but what about the part after the @ is that a constant?

Most of these are gmail.com accounts and have long strings on nonsense repeating characters similar to this:

xxxxxxxxxxxxxxxxxxSEZZSURGQkYyMDIxRkFDRUJPT0tCQVJDRUxOQVRXVFRFUjIwMjJORVdZRUFSCQVJDRUxOQVRXVFRFUjIwMjJORVdZRUFS@gmail.com

Other emails have different strings of characters.

TB = Thunderbird addon/extension FiltaQuilla allows to use RegExp 2 to create various types of filtering rules.

email address can have which valid characters, letters, symbols ? https://en.wikipedia.org/wiki/Email_address#Local-part

[a-zA-Z0-9\!\#\$\%\&\'\*\+\-\/\=\?\^\_\`\{\|\}\~\.]{151,}\@gmail\.com above filter rule detects/catches only those email-addresses which have 151 or more characters, then the @ at symbol then email-server / domain-name "gmail.com".
