Hello @pdonald

The port disappears because when you enable SSL/TLS the default port is 587 so there is no need for the port to be there.
If you use a different port then the port will remain visible.
when you click on the test button do you get an error? Also is this a windows or a linux PBX? Is it local or is it installed on the cloud?
Try to use a gmail account as a test to narrow down the cause of the issue

I'm also seeing issues: Windows install, Ver 15 using gmail.
Error: The remote certificate is invalid according to the validation procedure.
I'm using the same email settings as current system configs that are working. I did use the 3CX server to access gmail also.

Hello @business54

Can you send me a private message with a screenshot of the configuration and the error message you are referring to?

it sounds like you firewall inspects smtp connections and replaces googles ssl cert with an intermediate of your firewall... this is essentially what the message tells you...
