Areas for improvement

Things that could be improved in the design.

[danzuep]

Implement proper builder patterns.
The current implementation is more fluent than builder.

[danzuep]

Have a shared base/core/domain layer.

[danzuep]

Make it generic so libraries other than MailKit can be used.

[danzuep]

Add benchmark tests.

Hi, great library!
Perhaps something that is missing is being able to listen to flag changes on emails.

If I set up my monitor as such:
await _imapReceiverClient.MonitorFolder .SetMessageSummaryItems() .SetIgnoreExistingMailOnConnect() .OnMessageArrival(OnArrivalAsync) .IdleAsync(_cancel.Token);

There doesn't appear to be an extension method or handler for the IMailFolder.MessageFlagsChanged event.

Are there any plans to add this or have I missed something obvious?

[danzuep]

Thanks Mark, great idea! Is this something you are looking to use?

I've added an separate thread for this excellent idea.

Excellent! Yes, when I start my idle process I am ignoring any read emails in the inbox but I would like to process them once they become unread.
I then want to move the processed email to a sub folder, which I've seen can prove tricky if the ImapClient is busy in another thread, i.e. the idle process.

But for now, I just need the IMonitorFolder to have a method for OnMessageFlagsChanged if possible.

Thanks a lot!
