It only filters on the first instance of it. For example, consider the following header: Received: from deleted.invalid (0.0.0.0) by localhost; 9 Mar 03 13:16:48 -0500 Received: from 0.0.0.0 (EHLO deleted.invalid) (0.0.0.0) by mta180.mail.scd.yahoo.com with SMTP; 09 Mar 2003 07:43:12 -0800 (PST) Received: from n37.grp.scd.yahoo.com (n37.grp.scd.yahoo.com [66.218.66.105]) by deleted.invalid with SMTP id h29FhBZ71811 for <MY-EMAIL-ADDRESS@invalid>; Sun, 9 Mar 2003 08:43:12 -0700 (MST) Received: from [0.0.0.0] by n37.grp.scd.yahoo.com with NNFMP; 09 Mar 2003 15:43:02 -0000 X-Sender: DELETED X-Apparently-To: DELETED Received: (EGP: mail-8_2_6_1); 9 Mar 2003 15:43:00 -0000 Received: (qmail 87955 invoked from network); 9 Mar 2003 15:42:59 -0000 Received: from unknown (0.0.0.0) by m9.grp.scd.yahoo.com with QMQP; 9 Mar 2003 15:42:59 -0000 Received: from unknown (HELO web41206.mail.yahoo.com) (0.0.0.0) by mta1.grp.scd.yahoo.com with SMTP; 9 Mar 2003 15:43:01 -0000> Received: from [0.0.0.0] by web41206.mail.yahoo.com via HTTP; Sun, 09 Mar 2003 07:43:01 PST To: <BUY-OUR-JUNK@spam.invalid> From: <BUY-OUR-JUNK@spam.invalid> In this example, I may want to filter out "MY-EMAIL-ADDRESS@invalid" in the third received header, even though many more exist. Currently, it would only filter on the first header. Reproducible: Always Steps to Reproduce: 1. Create a "Received" header rule in mailnews to filter a string in any received header but the first. 2. Run the filter on the folder/account with this message. Actual Results: Message will not be filtered Expected Results: Message should be filtered.

Changing target to Thunderbird from Mailnews.

Each Received header will be searched if there are more then one. But only the first line of it while Received headers mostly consist of several lines. *** This bug has been marked as a duplicate of 124641 ***
