How to filter by part of a filename in Thunderbird?

Question

Mozilla Thunderbird

Hello, I need to create a filter by part of the file name in Thunderbird.
Example, you need to transfer an incoming letter from the attachment 124ffffff.doc to another folder. How can I do this, I can’t get it to work for several days.

in Bath there is a filter on the part of the file name, but Thunderbird does not. I use pop3, tell me how can I make such a filter.?
