WYSIWYG for your outgoing emails
MessageFont lets you set Apple Mail’s default composition font for new rich text outgoing messages.
It interfaces with Apple Mail by overriding the keyboard shortcuts for New Message, Reply, Reply All and Forward Message. It also has shortcuts for inserting and replacing text with properly font-formatted text in your new messages.
