Super slow scanning

I then added inbox to the scan other folders list and got scanning but extremely slow (many tens of minutes per scan) - like many people I have a few years of mail in my inbox and (it appears) that 3.0 rescans the entire mailbox every pass it was taking forever - I’ve moved most of the old mail to a new mailbox but the scan is still quite slow but usable

This is much faster in SpamSieve 3.0.2b1. It can now scan a mailbox with 10,000 or more messages in a fraction of a second.
