I just had another thought: Might it make sense to store sent mail together with normal messages?
A fundamental problem is that mutt's "Search" feature cannot search over multiple mailboxes. Thus, if I want to review a series of e-mails that I exchanged with someone about a specific topic, then it may be useful to be able to see both sides of the conversation. I'm thinking that it might make sense to keep only *new* mail in ~/Maildir/, though. For me, an e-mail message that I receive may represent something that I have to do (e.g. reply to the e-mail, do what the person in the e-mail told me to do, etc.). So, I could remove messages from my inbox only when I have done the action that is associated with that e-mail. This makes it less likely that I'll forget to do something (which has happened before; I can be quite forgetful at times). So perhaps: - New mail is sent to ~/Maildir/. - Messages that I have sent go to =old. - I save messages to =old when I'm done with them. - A daily cron job scans =old and moves 3-month-old messages into =archive.
