>> Whereas, if the MLM is explicitly told that the convention is in use >> within the ADMD (at least for this subscriber), This raises another hazard of a convention like this: it can lead to things like MLMs assuming that anything with a + (or whatever deliminiter is chosen) is an instance of this convention, leading to severe brokenness when faced with addresses at a site that doesn't work that way. FWIMBW, I'd prefer to see emphasis on the "nobody but the receiver and those with out-of-band knowledge of the receiver have any business assuming anything about local-parts" aspect. If my system happens to have an address with local-part *^%+_!^! (or, more plausibly, one+two) nobody without special knowledge of my system has any business inferring any structure from that; in particular, inferring that local-parts *^% (or one, respectively) even exist, much less bear any relationship to the full form, is broken - absent, of course, specific out-of-band reason to think the relevant mailer uses plussed addresses. >> That said, it has been suggested that MLMs might want to go a step >> further, and rewrite messages such that a message from >> <keith+something@example.net> copied to a mailing list which has a >> (Subaddress-enabled) subscriber of <keith+ietf@example.net> would >> cause the MLM to go as far as rewriting headers to the subscribed >> address. > This makes me nervous. Me too. Your reason strikes me as valid, but I'm actually more worried that implementors will lose that "(subaddress-enabled)" part and simply assume subaddresses - after all, it's Standard, right? - and end up sending mail to the wrong places. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse@rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
