I just downloaded version 16.something - looks like they have pulled the versioning in line with Firefox (what's with that, anyway? A new major version no every couple of months?)

My problem is that the Mac version, like many other Mac mail clients, is buggy, and there doesn't appear to be *any* client that can handle a large database of email (e.g. 47,000 messages taking up 11 GB) - what do other people do? This can't be a unique requirement, I know any number of people who use their email as a filing system.
