Hi Everyone! I’m pretty new to Hubspot and trying to send emails using the marketing tools, or one on one,to various agents and managers for my daughter who is seeking new reps. I am sending them one at a time and personalizing them in the body to that particular person. However, of the 4 I’ve sent so far, two were unopened and the other two keep bouncing with the following error message: | | | Your message couldn't be delivered to **xxxxxxxxxxx** because the remote server is misconfigured. See technical details below for more information. | | | | The response from the remote server was: 550 Please turn on SMTP Authentication in your mail client. [mail-wm1-f45.google.com](http://mail-wm1-f45.google.com/) [209.85.128.45]:43613 is not permitted to relay through this server without authentication.Does anyone know what this means or how I can fix it? I've tried resending several times with marketing email and one-on-one.thanks,Dawn | ---

Hi @UltraViolet , There is probably something wrong with your SMTP settings. Please check out this [post](https://knowledge.hubspot.com/email-tracking/troubleshoot-imap-inbox-connection) to see how you can configure these settings. ---

Well, this one may be above my paygrade. :). I’ve looked through the settings and think it’s all right. Also, if I send an email to one of my own email accounts or a friend, it works fine (although does end up in junk folder sometimes).
