#118 imap list SPECIAL-USE attributes missing for office365

[Alexej Lantuchov]

We are evaluating DavMail as a server-mode IMAP gateway to office365 and faced the following issue: RFC6154 SPECIAL-USE attributes are not returned by the LIST command.

Below are snippets of IMAP sessions outlining this problem, passing return (SPECIAL-USE) option doesn't effect the result.

Is it possible to get these attributes from DavMail?
If not, are there plans to support this?

• The direct IMAP session to outlook.office365.com

Note (\HasNoChildren \Sent) or (\HasNoChildren \Trash) attributes in the result.

I didn't know this RFC.
As Exchange already manages special folders this should be too difficult to implement.

Implementation available in trunk
