Recently our Service Provider reported our service as unabailble for about an hour - during which time some Method users weree assigning Activities.  The email alert emails bounced and an error message was shown - Email Send Failure Alert.  
My question is - when the service returns what would happen to the alert emails?  I read on the Forum that they try 14 times, each time after a minute wait.  However the service was down for an hour.
Many thanks
