For archiving purposes, I would like to copy/move all messages of a conversation in one folder, including sent messages and messages stored in different folders. I tried several things, like "Cmd+A" while one message of a conversation is selected, but nothing seems to work. Is there a way to do that?
The idea is the following: I use an IMAP account an whenever a project is finished, I move the corresponding folder on the server to an archive, e.g., from
./MailArchive. At the moment, all mails are included except the mails I sent. To get a complete archive, the sent mails should be in there as well.
