I consider RFC 976 an explanation of how some non-rfc 822 mailers do things at best. RFC 976 adds to the confusion by giving more credibility of the use of ! other than in the local part of the address. Use of % as a routing character has never been anything but a hack, as the csnet people who started it admit, and the need for it will disappear when MX records become universal. -- Bob Larson Arpa: Blarson@Ecla.Usc.Edu blarson@skat.usc.edu Uucp: {sdcrdcf,cit-vax}!oberon!skat!blarson Prime mailing list: info-prime-request%ais1@ecla.usc.edu oberon!ais1!info-prime-request
