I don't understand Jared's concern.  His DMARC policy, like mine, is p=none
which tells receivers to do nothing DMARC-y with our messages.  I don't get
any sort of blowback from nanog posts that I can recall seeing.

I'm sort of surprised that an org would have p=reject when its users use 
outside mailing lists. 

Unfortunately, we lost that battle a long time ago.  It's "more secure" and
"best practice" so go away.


Much like inline replies v top-posting and etc.. 

I did manage to get someone to flip the setting so hopefully I’m not getting a lot of bounce back from this e-mail.

Thanks to the kind soul who flipped the setting.
