Invalid email address when saving a new DNS

[rajeem]

When I try to add a new DNS and fill the email address field, the '@' symbol is replaced by dot '.' after saving. For example admin@example.com is saved as admin.example.com

Thats ok, because emails are saved using dotted email address. More info here http://www.htmlgoodies.com/beyond/webmaster/article.php/3473261
