But you have to deal with some problems. I was thinking about it for SM too,
to speed SM up.

You can ask the imap server for the current number of emails. You can ask
the  imap server for the highest message number(increases with every new
message). If this number change, you know there are new messages. That's easy.

You can also fetch the message body. If you put this data into a database,
you h ave what you want. I would store the headers in the database, but when
i reas a message, i would always connect to the imap server, so i get's
markes read there.

Problems:

What if you deleted a message with another imap client? The you need to
resyncronize both. Don't know if that's a big problem.


I would like to test this with SM. Let's see what we can do.
