dovecot - Feb 2016 - ANNOTATE plugin? Squirrel uses it for EXPIRATION information

Hi,

it seems that Squirrel mail uses Mailbox annotations for storing Expire
times on the Server. It's an Cyrus server currently. (I've no clue how
cyrexpire is able to read it's information from the annotiations)

Does dovecot support some similiar mechanism? Or - does anybody know
anything about how it's supposed to work on Cyrus and how it can be
emulated/simulated with dovecot?

Thanks in advance,

    Best regards from Dresden/Germany

maybe metadata could be used.

dovecot.conf:
   mail_location = maildir:~/Maildir/
   mail_attribute_dict = file:Maildir/dovecot-metadata
   imap_metadata = yes

$ doveadm mailbox metadata set -u user INBOX/subfolder /private/my_expire_info 5
-> is saved in ~user/Mailfir/dovecot-metadata

$ doveadm mailbox metadata get -u user INBOX/subfolder /private/my_expire_info
5

now you could iterate over all mailboxes and all users and do magic things.
unsolved: how could a user set values?

Hm.

    ANNOTATE RFC 5257
    METADATA RFC 5464

Does METADATA cover ANNOTATION? I'll try to find that out and I'll
report success or failure here on that lits.

I believe, that's done via the IMAP ANNOTATE extension. I see it for the
very first time and so I've to investigate it further.
