I love Apple Mail, but it simply can't handle the bulk of mail I have/receive/need readily available. I thought it was just the number of accounts I was using, but on my new machine I currently only have my personal one and it is DREADFULLY slow (I can't even delete messages in bulk, I have to break them up by scores; which may not seem that big a deal until you're deleting a sent box with 40,000 messages in it). Any suggestions for a Pro grade replacement? Something that can handle multiple accounts, moving large amounts of messages at once, bulk forwards, mail lists, etc.? Freeware preferred but shareware or payware is fine.
