Answer 1

For AWS users who work with Amazon SES in conjunction with PHPMailer, this error also appears when your "from" mail sender isn't a verified sender.

To add a verified sender:

1. Log in to your Amazon AWS console: https://console.aws.amazon.com

2. Select "Amazon SES" from your list of available AWS applications

3. Select, under "Verified Senders", the "Email Addresses" --> "Verify a new email address"

4. Navigate to that new sender's email, click the confirmation e-mail's link.

And you're all set.
