Donotcall.gov has no MX records. No reverse DNS on any of their outbound mail boxes. And they obviously are not processing bounces/complaints/etc. since nothing on that netblock has port 25 open.
Businesses that ask for email addresses know that a significant percentage of people can't type their own email address correctly. Each of those results in a bounce, or an undeliverable message sitting in an mqueue somewhere. It would not surprise me if they also reduced their Timeout.queuereturn to a few hours as well. Dealing with the bounces would be a nightmare, they've already got their handsful with the webservers and the outbound mail boxes. Sameer
