I agree and also use evolution because it feels more comfortable and well thought out than the alternatives.

Thunderbird feels wrong for some reason, and webmail doesn't let me have ten accounts in one place... I love being about to readily move an entire email folder to a different imap amount entirely with drag and drop.

I think it mostly just reminds me the most of Eudora so I just like it for being familiar.

(I've never encountered this bug, I guess I just don't have changing my signature in the workflow.)
