XF 1.3 Confirmation email not sending to registered users

Hello, I just got xenforo running at www.ngscholars.com/comm and I was liking it until I found out that newly registered users were not getting their email confirmation message. I tried to use one of my own emails to register and I go the following in the error log. What could be wrong please?

I have used both default and SMTP option.

This is a failure opening the connection to your SMTP server. If it's happening consistently, you need to use a different setup (such as a different SMTP server). It may be a connectivity issue between servers, a firewall, or some sort of SSL issue.
Thank you for the quick response. What would you recommend that I do? I cannot get started with this forum knowing that visitors can register but not confirm their email. What are my options?

I assume you're on a shared server.

If the default method doesn't work, you would need to contact your host to resolve that.

In terms of SMTP, you could try a different configuration for the server you're using, if available. Contact your SMTP provider for more details. If that doesn't work, you could try a different SMTP server. Finally, you may need to contact your host if all sorts of outbound connections are being blocked.

Last resort could be a different host/different server.

I am using Gmail as my SMTP server on 2 forum and so far it seems to be working for me so give that a go and see how it goes for you.
