Bennett Todd: > Outlaw people from receiving email on Windows, and we can > do away with all this sludge Heh. The base64 ambiguity isn't Windows MUAs issue ;-) Just tested MUAs for *nix: 1) kmail. data truncated, warning excellent! 2) pine. depending on input * data truncated, warning reported * decoding error reported not too bad... 3) mutt depending on input * decoding error reported * input after padding is decoded evil badness approaching! 4) emacs. similar to (3). Also, tested perl MIME::Base64 - data truncated, no warnings (which is good for MUA but bad for filters), uudecode - input after padding is decoded, cryptopp (opensource crypto and enconding library) - paddings are ignored. p.s. Windoze mustdie, *nix 4ever? ;-)
