andytibb on "[Plugin: WP Mail SMTP] Plugin sends to all domains except its own"

I'm using the WP-Mail-SMTP plugin in conjunction with the Fast Secure Contact Form plugin. It sends out test emails to any domain except the one it's hosted on (through GoDaddy). I followed the GoDaddy guide and set it up exactly as it wants. The SMTP test log says the message was delivered successfully, but it never comes through. Any suggestions are appreciated.

Thanks
