PROBLEM:


When attempting to send an email using our SMTP outgoing mail servers, you are seeing one of the following errors:



  • 550 Access denied - Invalid HELO name

  • Relaying Not Allowed


QUICK SOLUTION


The quick solution is that you need to enable the "outgoing mail server requires SMTP authentication" option in your mail client program.


DETAILED SOLUTION


In an effort to combat SPAM sent from our servers, we require all email accounts to authenticate with a valid username and password before they are allowed to send mail.


Any device sending mail through our email servers will need to enable the "Outgoing SMTP Authentication" option in the mail program that is sending the email. This includes computers, cell phones, smart phones, etc.


Below are step-by-step instructions for many of the popular email programs. This is not an all-inclusive list and we do our best to ensure that the information is accurate. If anything is incorrect, please let us know.
