Wow...I'm an idiot. I was setting up the new e-mail address askyanni@theyanni.com, for the new section of the website, and I realised something. When I had made e-mail addresses before like:

yanni@theyanni.com
the_nExt@theyanni.com

When it asked me to input a name for the addresses, I inputed the entire e-mail address I wanted, so actually I created the e-mail address

yanni@theyanni.com@theyanni.com

So Yeah, I feel like an idiot for it taking this long to realize. It also explains why I hadn't recieved certain e-mails that I know were sent. But oh well its fixed now.... :-P
