    Angry WHMCS SMTP error!

    hello,
    we got this smtp error with our WHMCS.

    Email Sending Failed - SMTP Error: Could not authenticate.

    is this due to our server?

    Yes this problem is within your server not because of WHMCS script.

    The problem is likely that WHMCS has somehow accepted a saved password into your SMTP settings fields.

    It's stored in tblconfiguration as 'SMTPUsername' and 'SMTPPassword'

    Just empty fix those fields.

    It means the username or password you are using is incorrect. Try to change the password for that mail account on the server, then use that new password with WHMCS.

    are you using your email to send the emails ? or Php script option in Whmcs ?
    this error may be coz of smtp setting not fine,
    double check your email & password that you have given in Whmcs settings.
