Type your message, and then click the Send button on the toolbar.
To use a mail account other than your default account, click the File menu, click Send Message Using, and then click the mail account you want.

If you are composing a message offline, click the File menu, and then click Send Later to save the message in the Outbox folder.

To send a message from within the Address Book, select the contact you want to send mail to (select multiple contacts by pressing CTRL while you click the contacts' names), and then click the Send Mail button on the toolbar.

To look up e-mail names in the Address Book and directory services, type the name, or part of the name, in the To box, click the Tools menu, and then click Check Names. Note that your directory services must be set up to check e-mail names.
