E.g. it took iOS a couple of years to start supporting it properly. And it is one of the better mobile email clients. Brian sent me a message/rfc822 wrapped version of his message, so I stuffed it into my Gmail, Yahoo, and Hotmail mailboxs after looking at it in Apple mail and Thuderbird and of course Alpine. Gmail flattens it to look like a text forward, Yahoo loses the headers on the wrappped message, Hotmail and Apple mail show it as an attachment you can download, Thunderbird and Alpine show all the relevant bits, but not in a particularly attractive way. In practice it's worse than rewriting the From: line to the mailing list's address, which is already far from good. R's, John
