We've been doing that here for a couple of weeks now, during which time I've sent it through most of the gateways, and it works! Since the RFC guarantees certain strings will never be used (and thus can be used for user-extensions), it's possible to choose something that will REMAIN "totally new and unused". Unfortunately, if you ever established it as a standard, you can bet some of those CAASH mailers would start rewriting it for you, just to help you out... actually I've been considering randomly choosing one of a large set of field names for each message, sufficiently large as to discourage including the list in any Sendmail rewriting grammar, to assure that it will be un-munged, until such time as "artifical" intelligence approaches the level of "genuine" intelligence... at which time (oh, never mind... that was a couple of years ago, in net.unix-wizards). We also use those extension-fields to capture the formerly-lost "remote from" UUCP lines into an X-UUCP-SENT field. -- Shyy-Anzr: J.
