The Opera email client is a slick and flexible interface that will satisfy almost all your email needs, and Opera integrates RSS feeds in this experience as well. Some may find the message editor lacking a bit in power, and the absence of support for encrypted email is unfortunate.

Mailsmith

Mailsmith, the email client from the makers of BBEdit, is just as powerful and feature-rich as the text editor.
It's a pity Mailsmith supports POP accounts only, and an—adequately empowering—rich-text editor could be a neat addition, too.
