[clue] opensource email clients?

[Mike Bean]

So I'm curious.  I heard that Thunderbird is discontinuing development, and
I was curious if the cluebies can recommend their preferred client?   To my
mind the problem with webclients is the lack of encryption/signing options
Now, I figure if Thunderbird becomes unusable, there's always evolution,
but I thought I'd ask the mailing list if they're comfortable recommending
other clients?
