I am late, but i would not do this. Some years ago, for example, the gnu.org people had a bug somewhere, and one of those headers (i could not find the thread in my archives on Monday, i wrote the admin by then, who fixed it) was duplicated. Now you can say that if those messages would have bounced, they would have realized the error by themselves and pretty fast. Yes. If they would have been discarded and collective status reports had been sent instead, no good, i think. In general i have no idea, but it seemed to have just worked in practice -- i believe they do send quite some emails every day -- and Postel made it happen. Maybe a levelled report facility should exist, with soft and hard errors, and if that would be soft, then yes. --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt) _______________________________________________ Ietf-dkim mailing list -- ietf-dkim@ietf.org To unsubscribe send an email to ietf-dkim-le...@ietf.org
