My email SMTP client is being blocked by the server
We have a VPS with you and on it we are trying to connect our email sending client (hosted on our domain foundfirst.com) with our SMTP relay server but it is giving the following error: https://www.screencast.com/t/J1lKg9t0ZBt
The support staff for our sending platform was able to connect with the same credentials from the sender installed on their own server, and here is what they said:

Our email sender is hosted in a subfolder on our domain foundfirst.com
What could be causing the software on our domain to be blocked from connecting to our SMTP relay server?
Thanks
