How do I create a new folder in Mutt

Question

I want to create a new folder from within Mutt. I use Maildir format to store the folders on the machine I am running Mutt on.

(I also view the mail remotely using courier IMAP but this doesnt involve Mutt)

Edited to clarify role of IMAP

Answer 1

c (change-folder), ? (list), Shift+C (create-mailbox)

Answer 2

If Mutt cannot create maildirs directly, it is easy to do it yourself. A "Maildir" format mail directory has nothing special except for three subdirectories cur/, new/ and tmp/ inside.

Assuming you want a directory named something, and your mail is kept under ~/mail/:

mkdir -p ~/mail/something/{cur,new,tmp}

Equivalent to:

mkdir ~/mail/something ~/mail/something/cur ~/mail/something/new ~/mail/something/tmp

---

Edit: Courier uses an ... unusual convention of maildir naming: if you want a hierarchy of, for example, Archive/2010/06, the folder name will be ~/mail/.Archive.2010.06/ while most other IMAP daemons would use ~/mail/Archive/2010/06/.

Answer 3

I usually just save some email to new not-yet-existing folder, and mutt creates the folder for me.

For me it's pretty intuitive, as there is no point in having folder without mails in it, so I just create it by saving there first mails that should go there.
