User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; rv:1.7.3) Gecko/20040913 Firefox/0.10 StumbleUpon/1.998 Build Identifier: Mozilla Thunderbird version 0.8 (20040913) It would be very handy to save replies and forwards in the same folder as the original message. That way people who organize ongoing correspondances into folders can avoid having to repeatedly move sent messages into the same folder as the message they are replying to. Reproducible: Always Steps to Reproduce: 1. Move a message into a folder. 2. Reply to the message. Actual Results: The reply is put into the "Sent" folder, not the original folder. Expected Results: The reply message should have been put in the same folder as the original message. This could be controled by an option, if you think some people want the current behavior.

This is basically Seamonkey bug 177040, with the added wrinkle of including forwards.

Thunderbird's ability to thread message conversations is undermined by this bug because replies do not automatically form part of the conversation as they are placed in the Sent folder. As stated above, the user has to manually sort sent messages which negates the power of the threading feature. This bug is important because of the way it affects conversation threads.

Coding is taking place on this over in 301084, so DUPing to that bug. *** This bug has been marked as a duplicate of 301084 ***
