Thanks for the suggestion, Shivam! I can definitely see the benefit in allowing the system to auto-update, and it's something we'd like to see in the future. However, this functionality will not make it into SmarterMail 16.
I'm going to move this to the standard SmarterMail category so that this request is not lost when we close the SmarterMail 16.x BETA Category down the road.
Thanks!
