How to Add Mail Signatures in Mac OS X Lion
If you’d rather not type your whole signature every time you send an e-mail message, you don’t have to with Mail in Mac OS X Lion. If you create canned signatures, you can use them in outgoing OS X Lion Mail messages without typing a single character.
Here’s how it works:
Choose Mail→Preferences or press Command+, (that’s Command+comma).
Click the Signatures icon in the Preferences window’s toolbar.
Click the name of the mail account you want to create this signature for in the left column.
Click the little + sign at the bottom of the middle column to create a new, blank signature.
Type a descriptive name for this signature to replace the default name Signature #1.
Type the signature exactly as you want it to appear in outgoing messages in the right column.
Drag the name you’ve assigned this signature onto the mail account you’re using it with.
That’s about it for signatures. If you have more than one signature, you can choose the one you want to use as the default for each account: Choose the account in the column on the left; then choose the appropriate signature from the Choose Signature pop-up menu.
If you have more than one signature, another cool thing happens: A Signature menu appears in new messages, so you can choose a signature other than the one you chose from the pop-up menu as the default.
