I’m using Google Apps and sending emails from my own domain address but sometime get “Failure Notice” message that says ‘Sorry, we were unable to deliver your message to the following address.’. It seems that we need to create a SPF record and a DKIM record for your domain with Google Apps.

2 ways to verify that SPF and DKIM are configured properly
There are 2 ways to verify after you’ve completed the SPF & DKIM setup.
- 1. Send an email from your Google email account to firstname.lastname@example.org.
It’s Port25’s authentication verifier service at verifier.port25.com. The service allows email senders to perform a simple check of various sender authentication mechanisms. It is provided free of charge, in the hope that it is useful to the email community.
