correct way to implement Connector interface

[CognoscereK]

Hello, I have been trying to use gluon to implement an IMAP server, I really liked the library but I'm still struggling in how to make it work the way the intended way.

For what I understood by looking the code I need to implement a Connector interface and this connector will be the high-level API to main IMAP features(like creating mailboxes/messages/moving stuff etc) so I took the Dummy as base and implemented a version of the connector myself, the issue is: it works fine for creating new messages and so on but the moment I restart the server the connector loses its internal state making it desynchronized from the storage/database, so if I try to update a message flag it fails because the message exist in the storage/database but do not exist in the Connector.

Should I be populating the connector beforehand with messages from the database? This doesn't not seem right since it's not so straightforward and would make the server consume a lot of memory, am I doing something wrong?
