registration email server bug

Hello,
After submitting registration details i got an email server error.
Domain name starts with smtp and leads to a blank page with text This is a private email server.
So no confirmation email and i guess that is the reason torrent uploading doesn’t work.

Should work now!

I have Your email address hasn't been confirmed yet notification but trying to resend email several time on different days and still nothing arrived.
Which email providers are supported here? I trying to verify gmail address.
