Your problem
My problem is:

Trying to use Mailbaby as a SMTP server but for some reason I can’t get it to work. I constantly get the error message:
“Connection could not be established with host relay.mailbaby.net :stream_socket_client(): unable to connect to relay.mailbaby.net:587 (Connection refused)”

But I can send via mailbaby with other clients. Did anyone experience the same error?

Hi, are you sure your port 587 is open on your server?
Amazon likes to block it btw.

Thanks for getting back to me @joeyk , port is open.
