Invalid Security Certificate for the server. Try changing the incoming port to 25, without and try again.

Hi,

I've tried to add my custom smtp server for 2 days now. I have valid SSL certificate and it's still not working. I'm trying to use my smtp server on port 587 with TLS Auth.

I've tested my cert in Thunderbird and Google Mail. It works like a charm, but here i've got error.

Can you help me to solve this problem?

Thank you!
