I'm using PHPMailer and I'm getting the following error when trying to send email: Message could not be sent. Mailer Error: The following From address failed: xxx@xxxxxx.com. How can I fix this?
There are a few reasons why you may be seeing this error message. The two most popular reasons are:
1.) You need to use SMTP Authentication in your PHPMailer script so it can authenticate with the server to send email.
2.) You are using an older version of PHPMailer. You should upgrade to the most recent version of the program.
