when a user sending a bulk email, our smtp relay server (out source), bounce back with
#554 5.7.1 burst rate limit exceeded
so according to the relay support, it only allow 100 email per 10 mins and 500 per day
our users don't really send 500 email out per day, but could possible send 100 email within 10 mins period (a bulk email)
so my question is, is it possible to configure it on Exchange 2010 server with some type of policy resolve issue above?
