EM-3609
The mail server host cannot be used
Why it happens
Rabt connects only to mail servers on the public internet, on the usual SMTP ports (25, 465, 587 or 2525). This server is a local name or an address in a private or reserved network, or the port is not allowed.
What to do
Enter the public SMTP server name your email provider gives (such as smtp.example.com) with one of the allowed ports.
