some while ago I also encountered this problem. The server admin is also not very helpful, but from what i have already done, this is the thing that must be checked :

1. Host, this is the address of the SMTP server, if you want to connect to some server, i believe this is not localhost . Example : mail.mycompany.com
2. SMTPsecure, there are some method for securing transmission, you can test using SSL or TLS or STARTTLS
3. Port, test for the correct port. Commonly it uses port 465, but it can be other. For example STARTTLS uses port 587.
4. You can try to analyze the output debug message regarding your error.

Please correct me if i'm wrong.
