Basically, I would like email to queue up in SQL Monitor. In the event an email fails to send (account locked out, mail server down, etc), having the email just fail to send is not the desired result. When problems are resolved, the email should send.
For example, lets say IT is doing scheduled maintenance on the email server and during that window one of the SQL instances shuts itself down due to an error (for arguments sake, lets say out of disk). SQL Monitor will see it go offline and try to send out the alert but fail because the mail server is down. When the mail server comes back up, I still want to be notified as it is better to have a late notification than no notification. I'd rather see that the SQL instance went down an hour ago and the notification took a while to arrive than get a phone call telling me that my SQL instance is down.
