+1.
I preferred the "let's honor the policy" list system adaption
approach. It was the simplest, less programmatic approach. I did get
some initial complaints from users who wanted to continue using their
"junk" ESP email addresses like yahoo.com, aol.com and now icloud.com
accounts and other larger esp domain accounts with restrictive mail
policies who switched to restrictive policies. They understood the
dilemma and used other domains - problem solved.
