Creating a filter for email pretending to be from my ISP Sonic.net

Thunderbird Junk email and spam

A substantial portion of email spam that I receive has a couple of characteristics: - the subject line includes "Sonic", and - the sender is plainly not Sonic.

For example:

Return-Path: <live1@tomokawasaki.or.jp> Received: from tomokawasaki.or.jp (tomokawasaki.or.jp [122.1.223.161]) by mwb-sdgw-mts-005c1.ocn.ad.jp (Postfix) with ESMTP id 063B61400008F for <ronks@sonic.net>; Sun, 19 Jul 2026 07:07:06 +0900 (JST) From: =?UTF-8?B?U29uaWMg0JLRlmxs0ZbQv2c=?= <live1@tomokawasaki.or.jp> (From translates to "Sonic Billing" here; in other spam it is cleartext) Subject: Automatic Payment Unsuccessful To: <ronks@sonic.net>

I am wondering if it is possible to construct a filter that says basically: If Subject includes Sonic AND From does not include Sonic Then Send to Trash (or mark as spam or whatever)

Can this be done?

Yes, set the filter as subject contains sonic and sender does not contain sonic
