I do see a number of entries in the Error log like this...
Application Stopping. Reason: A change was made to the application level configuration
...some of which were made in the wee hours of the morning when I know I was asleep. Besides my service provider, I'm the only one who should be able to make any app level config changes, so these make me a bit nervous. Does SmarterMail do any sort of automatic updates that might take place in the early morning hours?
