I've just run the exbpa tool over our environment and one of the issues it flags up is the incoming / outgoing message size is set to high (40mb), is this a real risk? What are the problems/issues with such a high value?
What if a user genuinely does need to send and receive large emails? if you configure it to default of 10mb can this cause more problems than it solves? surely there are instances whereby mail needs to be >10mb due to attachments..
