Using Mail.app but have been looking for a replacement since 10.0 ....

- Mutt - is nice but I'm way too lazy to configure it on all the macs and other computers I need to use, and I can't just ssh or ARD on the work or home mac either.
- Kmail - is nice but feels pointless on OS X
- Anything mozilla based : still no integration with AddressBook, and way more annoyance getting the encryption working
- Pine : err no. Can't use sendmail the way I'd prefer at work, so need to stick to the usual mail applications
- Eudora : tried a month ago the last time. Still the feel and touch it had in the 1990s, and I'm not sure I like that any more
- Gyazmail : ... stuck in the gui and features of 10.3
- Entourage : keeping your mac microsoft-free: priceless

So after trying again everything from mutt to sea monkey and eudora to pine via gyazmail, nothing was what I wanted. Or rather needed.
- support for 2 GB + mailboxes, I don't like splitting them manually
- a lot faster and better search than in mail.app
- smarter filters than mail.app
- needs GPG support
- mail rules that work (so no more magically disappearing messages)
- addressbook seamless operability

Too bad there isn't anything like Adium for Mail...
