RFC 6154 [1] defines an IMAP LIST extension for SPECIAL-USE mailboxes. SPECIAL-USE mailboxes can tell the MUA they are meant for \Sent, \Trash etc. purposes.
It would be great if mutt supported this feature on the client side and mapped its own "special use mailboxes" i.e. $record and $postponed when an IMAP server announced the SPECIAL-USE" capability string in response to an IMAP CAPABILITY command. p@rick [1] <http://tools.ietf.org/rfc/rfc6154.txt> -- Postfix - Einrichtung, Betrieb und Wartung <http://www.postfix-buch.com> saslfinger (debugging SMTP AUTH): <http://postfix.state-of-mind.de/patrick.koetter/saslfinger/>
