Feedback

executiontimeout is case sensitive should be executionTimeout with a capital "T"

Also you will need to edit this file each time you do an upgrade of SmarterMail.

Errors clients receive using IE, FireFox or Chrome are "Your connection has been reset", and Network Error, also once in a while just says timeout.

Error in SmarterMail Log is : System.Exception: Null exception (likely a 404 or something else produced by IIS)

Default Timeout is 1 min 50 seconds, use this KB to increase the default.
