MUA's creating headers for their own internal purposes is a dangerous idea. But many do it. This may be the tip of the iceberg here. Maybe there's a way to protect headers from being pre-filled. How about something like this? Create header names spaces Not-For-Transfer-*: X-Not-For-Transfer-*: header name space (the second is a subset of the existing X-*: namespace) Modify the SMTP standard to the effect that MTAs MUST strip all [X-]Not-For-Transfer-*: headers Grandfather BCC as a synonym for Not-For-Transfer-BCC: [EMAIL PROTECTED] 805.964.4554 x902 Hispanic Business Inc./HireDiversity.com Software Engineer perl -e"map{y/a-z/l-za-k/;print}shift" "Jjhi pcdiwtg Ptga wprztg,"
