Looking for an easy WordPress backup solution, i decided to give several plugins a try. One of them was BackWPup. While testing it out, i ran into an issue trying to send backups via email. It was due to the DMARC policy on my domain. Below is an email i received (in Spam) when attempting to do the email backup option.
Quick trick to circumvent this issue is to set the “From” address in the plugin settings to [email protected] and voila, you should then be able to do the email backup now.
This “trick” can be used for any plugins that need to send email, particularly if you’re going to send from an email on your own domain.
