I have a couple of mailboxes, each with its own SMTP profile. My work box has my full name and work title in the signature of its SMTP profile so I can send work related email with a work signature. If I create a new email from that mailbox, the signature added is the correct one. However, if I forward an email I received in that box, then the signature added is the default one (Sent from ChatterEmail etc.) and not my signature. I don't know where this signature is coming from and how to change it, and it only happens when I forward mail, not create it. Ideas?

Last time I tried it was with 1.0.5rc9.
