So I just set up my first site and I'm learning the ropes with it. I'm going through feature by feature and figuring things out. I made an email account for the site and to make sure I did it right I emailed my gmail account with it. This is what they sent me.

I just made this site yesterday, and this is the first email sent from it. Has google already decided to block me all together for some reason? Even after I added the site to my contacts on gmail it still blockes me.
