That's not the best written article I've seen... The problem he's resolving is called backscatter FWIW. The change pushes responsibility for generating NDRs back on the sending MTA, which in general is a good thing. The only place this might cause problems is if you have a gateway box doing pre-filtering as it would now be responsible for generating the NDRs (so you've just pushed the problem back one hop). Recipient verification should take place at the perimeter of your messaging network. Assuming Exchange is the perimeter of your network, this is generally a good practice to implement. If you're not logging your SMTP protocol conversations now (shame on you), you should if you implement this change as it will be the only record of misaddressed inbound messages once the change takes effect.
