So I need a new email client. I've been thinking since reading the article in this month's MacWorld and there don't seem to be any great ones out there. Here's a partial list of features I need:

• Handle IMAP and POP mail
• Ability to import large email stores
• Mail must be stored in a standard format
• Mail cannot be stored in a single file
• Inline spell checking
• Read HTML email

So in short there is not an emailer out there that will do that. The big compromise at this point is between Apple's Mail which does HTML interpretation well but has terrible filtering and Eudora which has wonderful filtering features and lacks in displaying HTML formatted email.
