To set up a new email account in Postbox, navigate to the File menu and select New > Mail Account.
Enter your full name (as shown to others), your email address, and password, then click the Continue button.
By default, Postbox's New Account wizard selects IMAP as the type of protocol your new account uses, as we highly recommend this instead of POP.
However, if you wish to use POP instead, you can change this on the email settings confirmation screen.
