It appears that Alessandro Vesely <vesely@tana.it> said: >IMHO at least an appendix should say that if you can't do anything better you >have to rewrite From: with examples of legitimate display-phrase, expanding a >bit the first bullet in Section 11.4. That can also be a good place to explain >the kind of damage DMARC causes. Absolutely not. This sort of thing is utterly outside the scope of our job and wasting time on it just further delays our already extremely late work. R's, John
