📧 Introduction

If you're experiencing issues sending emails and your email provider is GoDaddy, this article is for you.

Many GoDaddy customers who have been automatically upgraded to Microsoft 365 accounts, and they may encounter problems when sending emails through the SMTP protocol. This is particularly relevant if you're using Mailbird Next with an IMAP account, as SMTP is the protocol responsible for sending emails.

🛠️ Solution

If you’ve received an error message stating "SmtpClientAuthentication is disabled" (or something similar), don’t worry, this can be fixed.

To continue using your GoDaddy email as an IMAP account in Mailbird Next, you need to enable SMTP Authentication on your GoDaddy account. This setting ensures that the email-sending protocol functions correctly.

👉 GoDaddy has a step-by-step guide on how to enable SMTP Authentication. You can access it here:
