Issue: confirm your e-mail address not possible

I had the problem, that since the 26th of April none of the notification emails arrived me anymore ... ...
since I had the problem in December of 2012 for the first time and there I just changed my email address to get it working again (still don't know why it stopped working in the first place, but I was happy that everything was back to normal)

today I tried it again:

• I changed my email address
• BUT the email to confirm my e-mail address did not arrive!!!
• I changed my email address again
• no confirmation e-mail
• I changed my email address again (every time another email address)
• no confirmation e-mail

now I'm really stuck ... tried all my email addresses ... ...

and I have this message on top of every site on aarin:

I don't want my account to be deleted!!! ... ...
HELP PLEASE!!!
