I had a message (with attachments) sitting in my outlook folder which for some reason sent itself about 6 times before getting blocked.  I am completely fine with this; you did the right thin based on exceeding my daily limit and I have fixed the issue.  However, what I would expect is that the next day I get my mails back again, altho I am in NZ which is GMT+12 so it may still be the same day where your servers reside.  Also; how do I change my 'master account' that I used when I set up my account; it has long since expired.  I do not really want to have a second account as a backup
