Amazon SES Strange Email Format

amazon-sesemail

My email logs are filling up with bounced emails being sent from my domain with a From header formatted like so:

root@support@mydomain.com

What is causing this?

Best Answer

Invalid MAIL FROM address provided (in reply to MAIL FROM command)

When sending via SES, you need to set your From: header to one of the "verified" email addresses you configured when setting up SES for your AWS account.

You're setting your From: address to root@support@mydomain.com, which is an invalid email address. You need to set this to a valid email address that you've verifed through the SES console (or API).
