[sf-lug] threaded mail reader that includes sent messages?

[Michael Shiloh]

Every so often I am reminded that when sorting messages by threads, no 
mail tool that I'm familiar with is able to include sent messages as 
well as received messages.

(I am told that Google mail does this, but for some reason I don't want 
to use a web based mail tool.)

When I am reminded of this lacking feature, I think: "Surely my 
knowledge is dated, and by now some mail tool must support this feature".

Thus my question: Is anyone aware of a mail reader with this feature?

Thanks,
Michael
