I was wondering if anyone knows a way to do this: Right now i'm using an html e-mail client called Horde which allows me to have multiple from addresses linked to signatures as well. I can switch between them instantly and send mail from wherever I want to. I know this feature is available in Eudora, but does anyone know a way to do it in Mail? I really like Mail because it's small and integrated, but I want to be able to use it for everything else. The reason I can't setup a few more accounts is because everything I have forwards to one account AND I have a lot of random names because I own a domain and can receive all the mail sent to the domain at one address, but send from any. I hope this makes sense...
