Mailpile should automatically stop trying to re-check a mailbox/folder which has been deleted from the source/server.

This should be done in such a way that if the mailbox reappears, polling starts again. This should be relatively straightforward, mostly we need to make sure that each individual mailbox type communicates clearly that it's "gone" (not just temporarily unavailable) and the master

Ideally, the ImapClientDemo sample would also demo IDLE support and restoring the connection if/when it gets dropped.

Here is a compilation of up-to-date RFCs related to IMAP:

• 2177 - IDLE Extension: https://tools.ietf.org/html/rfc2177
• 2342 - NAMESPACE Extension: https://tools.ietf.org/html/rfc2342
• 2971 - ID Extension: https://tools.ietf.org/html/rfc2971
• 3348 - CHILDREN Extension: https://tools.ietf.org/html/rfc3348
• 3501 - IMAP 4rev1: https://tools.ietf.org/html/rfc3501
• 3502 - MULTIAPPEND Exten

It would be prudent to include relevant information from the latest original website, for posterity. This should be moved to a relevant structure, for example a /docs directory.

Hey :)

It would be great if documentation, like the "getTextBody" of Message::Class per example, mentionned it could return false (or just bool, but it return hardly false so...).

At first, I was not expecting this, since I saw "string" as return type.
Looking into the code, I understood why I got false, of course and I therefore wrote some code in consequence.
Or maybe... Make it return a

Great job on getting IMAP support into Flutter, much appreciated.

However, as a relative newcomer to the IMAP protocol, I'm finding it quite challenging to know how to use your library to perform common tasks. I also find the ImapResponse class quite difficult to work with; there are many different fields and it's not clear which ones will contain the answer to my commands.

I imagine a lot
