If you take a look in the PHPMailer unit tests, there is an example of how to set up DKIM.

Here are the basics beyond what you already need to do to send a message (obviously change the domain, key path and selector to match your config, and add a passphrase if you use one); this also assumes that you are intending to sign using the same identifier as your From address:

$mail->DKIM_domain = 'example.com'; $mail->DKIM_private = '/path/to/my/private.key'; $mail->DKIM_selector = 'phpmailer'; $mail->DKIM_passphrase = ''; $mail->DKIM_identity = $mail->From; 

When you send() the message (and not before), it will use these settings to generate a DKIM signature.
