Trying to send email to from my work to test my harbingerbeer email account I'm at a loss. I've added mx records and txt spf entries to no avail. Below is the error im getting and I'm pretty sure most emails are being blocked this way.

Thanks,

***SOLVED***
I struggled with this error for many hours, and anyone routing emails to an external server such as google will run into this problem.
1) Make sure you are in the advanced view of CPanel otherwise you won't find the settings you need (at the top of X10Hosting page click "Switch Theme", this does nor than change the font and colours!)
2) go into "Email Authentication" and scroll down to "Include List (INCLUDE)", use the "Add" button, in my case the domain I needed to add was "google.com" because that's who is providing the email servers. In OP's case he would add "breeeze.se.edu". The explanation is that the SPF (Sender Policy Framework) records must be updated to allow the external MX to deliver mails, otherwise the mails will be rejected citing authentication issues.
3) I figured this out from the following URL, it may help https://bobcares.com/blog/2-non-obv...l-exchange-servers-and-what-to-do-about-them/
