Any decent alternatives to Thunderbird? I have mine set up to fetch emails from multiple addresses, a mix of POP and IMAP.

Eudora and Claws are probably your best bet.
I am looking at Mailbird - it is not free but it is cheap in my view. But there are many alternatives.
Somewhere in this thread is a post with a Wiki link for a Wiki page that has a long list of 3rd party Email client applications. I forget which one it is, but it is in this thread somewhere.
