Actually, the MUA and MTA should be completely transparent in this regard. That's a heck of a lot easier to accomplish than to change all MUAs to conform to a given transformation standard. There is really no good reaon why existing mailers should fiddle around with the 8th bit. If you try to hack things by using encoding features at the MUA level, you'll just get into trouble later, e.g. when using the MTA for saving a piece of mail into a file or stuffing it through a pipe into an arbitrary program (common in sendmail, for example). In this country we use elm, smail and sendmail (along with news), which are fully transparent. We therefore use ISO 8859/1 exclusively for all mail (and news). Most programs involved need some hacking to accomplish this, due to all sorts of silly assumptions used by the programs. Stripping of the 8th bit is never *needed* at the MUA or MTA levels, but presumably it is very tempting for an 7-bit ascii-speaker to use the 8th bit for something else :-) What we need is for more companies to distribute clean mailers. Some already do this (HP, to name one), but others do not (Sun, to name another) .
