TIP
When I have multiple signatures, how can I choose which signature Mail
adds automatically?
Follow steps 1 to 4 to display the signature preferences and choose an account. Click
and then click the signature you want to insert automatically into each message. If you
prefer to add a signature manually, click None instead of a signature. Click Close ( ) to
close the Mail preferences.
