Email notification doesn't work

[Dr.Wackelzahn_apc]

Hi there,

I'm quite confused, as I've already tried different configurations, but none didn't work.

I'm using: AP8959EU3

Configured the TCP and DNS and tested the DNS successfully.

But neither the 465 nor the 587 port at the Email configuration work. Testing the configuration results always in the report: "Test e-mail failed; SMTP configuration error."

Is there any way to get more detailed information, at what point the SMTP configuration fails?

Thanks a lot.!
