Hi Tom,

Just a thought. I take it you are with iiNet now, hence the iiNet mailer 
daemon. You may have your wife's old address in an address book somewhere and 
inadvertently sent it an email. Which email account was the notification 
directed to? Have a look in the sent folder of that account from as many 
machines as you use that account on and see if there is an email accidentally 
addressed to the old account.

Regards,
Carlo
