This may be of use to you, I use my Exchange Mail Server for emails so it may differ if you use the email system supplied with the hosting.
Option 1 for general emails (new user register etc.) i have just setup a webcontact@mydomaiin.com address and this is received by my mail server and redistributed on a normal Exchange distribution list.
Option 2 For various account updates etc that users make I wanted the notification email to go to all of my personal emails so I would pick it up regardless of where I was so I set up X numbers of users giving each one one of my email addresses, made them administrators and ticked the notification box. None of the users are authorised and that doesn't seem to matter so when a user makes a change the notification is sent to all administrator accounts.
