It's been good enough for past near 20 years, fail to see why WE should change, just to appease lazy system admins, if they can't do their job properly, maybe their employers should know, so they can be replaced by someone who will do the job properly.

Not to call anyone out in particular, the general contempt some sysadmins show for their users is phenomenal-- sometimes I think people forget why we have these networks in place. We run these networks to service a customer or business need, not to give you toys to play with during the day.

If the customer isn't getting their mail, you're not doing your job. You can't dismiss the person with "oh the other end is doing something I don't like so I'm rejecting their email"

So what if someone on the other end of the world haven't set up rDNS properly on a box? Google don't set up any rDNS on much of their network infrastructure, which bothers me, shall I blackhole their traffic? I bet that'd last a whole 30 seconds before someone bitches me out.
