Even better, try explaining it to her even more senior, and non-technical, boss. The technical term for doing that is "death wish". While I've been an advocate, for many years, of tough "enforcing the rules is the only way to shake out the trash and make forward progress" policies, the reality, as Ned points out, is that the vast majority of users feel a lot more strongly about the mail being delivered if that is at all possible than they do about any degree of rule-enforcing and moralizing. Even if they agree with rule-enforcing in principle, they are "willing" to make an exception every single time there is a question about something of importance to them getting through. There are some important principles here which apply to SMTP extensions work, to DRUMS, etc. * Ultimately, the worst thing that can happen to a standard is for people to ignore it as irrelevant. The fastest way to become irrelevant is to "require" people to do things that violate their good sense and/or business interests. * Any rule that is made that _requires_ bouncing mail that could otherwise be delivered will be ignored by almost every for-profit vendor who intends to stay in business and by almost every not-for-profit producer who wants to see his or her code in general use. The exceptions arise with vendors who have purists as customers (purists are few and usually unprofitable) and with reference implementations that are written to demonstrate The Right Way to do something, rather than how to get the mail through. * And any rule that _requires_ massive inefficiency in mail handling will be ignored by nearly as many vendors/producers as a rule that requires bouncing mail. As with delivery, the users tend to prefer performance to religious arguments. john
