Please define signing...:
The cryptographic variant is encrypting portion of the header that you "encrypt"/"hash" using a private/ public key pair so other ca verify you sent the mail. This needs the same pretext as encryption. (only you private key on the server) ... so see above.
Signing as in -- on a line with something beneath it...
That is easy. Go to settings, identity, and fill out the textbox for it. And mark it as html if that is needed.
Be aware to not send your autograph in a picture, otherwise anybody can photoshop that into any letter.
