[AusNOG] IPv6 reverse DNS and Mail ...

[Terry Sweetser (SkyMesh CTO)]

I would consider the lack of a real and valid rev.dns entry for any 
corporate, government or provider mail server to indicate that something 
is not kosher.

If your customers, clients and/or staff can not receive email due to 
automated policies blocking the sender, that's an issue for the sender's 
system admins: they have problem that will not be fixed by the rest of 
the internet giving them uncontrolled access to most of the internet's 
mail servers.
