Hi,
Hi Stephan,
On an IMAP server mailing list I participated in a discussion about the new the IMAP LIST Extension for Special-Use Mailboxes (RFC 6154). In a nutshell, this extension allows identifying special-use mailboxes to an IMAP client. Special-use can for instance be a junk, trash, drafts, or archive folder. This way clients can easily identify such folders and use them without explicit user configuration.

At some point, the idea was raised to extend the Sieve language with similar means. It could for instance be useful to have a special version of the fileinto command that files the message into the default folder for a particular special-use, e.g. `fileinto :special_use "\\Junk";'. This can be particularly useful for global scripts outside the user's control. Through metadata support it is already possible to find out whether a folder has a special-use tag, but conversely it is not possible to find out which folders have a particular tag or what folder would be the default choice for that tag (note that the notion of a default folder for a particular special-use is missing in RFC 6154, which may be a problem).

My question is: do you think it is useful to have a Sieve SPECIAL-USE counterpart? And in what form?
This looks interesting to me. Your proposal above looks fine to me.
