error 73 sending email from Amazon server

[Richard I]

hello there,
I have posted a query about an error 73 previously, when trying to send an email using "Send email in a process"
and the situation was resolved by my importing the latest Clanet.dll
My current problem is that the app will run and send emails from the app running on my Windows 10 pc but not on an amazon server, where I want to host the app.
I have copied in all the dlls I think I need and the error is Fatal error n 534 - 5.7.1
and the error occurred in netEmailsend.process
Im using gmail with Port 465
The password is correct.
I have not set any outbound ports on the amazon server other than "All"

What could I be missing please?
Thanks
Richard

Errors of the form
- 5.7.1
are server-side errors reported by the server when your program tries to send an email to it.

As such the exact text of the error message there would be useful to understand.

An even better understanding will come if you run NetDemo.exe on the affected machine, and then set that up with all the email settings and send an email from there. The Log tab there then shows the whole conversation which should make the error easy to diagnose. Feel free to paste that log here.

cheers
Bruce
