We send out about 1800 emails each month. For the past 2 months it has been bogging down our network (using 99.2%) of our T1 while trying to send the emails. We haven't experienced any issues before until the last 2 months. Is it possbile a setting on Exchange got changed? Our Core Processor said that if Exchange is set to send emails all at once, then this would clog up our T1 but if it was set to send emails individually, then shouldn't use up bandwidth. Where might I find on our Exchange Server to check this? Or is there any other solutions to this issue?
