This is doubly
true since the ADSP RFC rather specifically says that you shouldn't
mark a domain discardable if its users send mail to lists.
Only if you care about the mail being delivered. I think that if we do this
BCP, we should give some advice about what, say, a company like, oh say, paypal
ought to do consider if they want to set adsp discardable. Like:
1) make people who want to contribute to lists on a the corpro accounts get
a gmail account
2) create new external/non-discardable accounts in a subdomain for that tiny
fraction of the population that needs to post to lists from a corpro
account
3) etc.
Since this is a bcp, it doesn't have to be generalizable to every conceivable
setup; it's just advice for the common cases, which corpro and isp mail
certainly
are.
