Error when using SMTP ocx

I am using SMTP OCX for sending emails from NAV, just because it has HTML support. Any ways, i get this error

This message is for C/AL programmers:

The call to member Send failed. SmtpMailXControl1.SmtpMailX returned the following message:
10061:Connection refused

but everything seems to be ok. Why do i get this error?

any ideas?

From the error. It could be a permission problem. Check the security settings on the SMTP server.

On another note.

I would personally use this:
