If you happen to be sending e-mail through an application, most have built-in functionality that allows you to break up bulk e-mail and only send every X seconds or Y minutes, or should. I know way back in 2005, forum software (vBulletin) was using something similar, so modern applications should have something similar to prevent all e-mail being sent at the same time.
You can modify Postfix configuration as well, as noted by @hansen , though I would also look to your application to see if there are configurable options there as well.
