SetNobodyAlias()
From Rackspace Email & Apps API
This function will add a "catch-all" account. Catch-all accounts are not recommended! Many spammers use "directory harvest attacks" that will try to send email to random list of possible usernames on a domain-- a catch-all alias will allow all of those usernames to appear valid and will try to receive that email.
Input Parameters
Three strings:
Administrative username, Administrative password, Domain name, Mailbox name of account to act as catch-all (part before the @ symbol of the email address)
Return Values
If successful, the return value of the function will be 1.
