A few ideas on that:
- MDA/MUA would definitely be the better place to do that. There are just so many of them - and we should tell microsoft... - general scrubbing of to/cc could be switched off by config, so it happens only if there is an ical attachment found. This makes sence because in this case you have no chance as a user to avoid the disclosure - we could have an opt-in or opt-out header field or a subject keyword like NOFILTER. I know, this is probably only a solution for nerds .... - there could be a whitelist of senders - btw. the number of addresses allowed in cc and to is also a config option. \Magnus -- Dr. Magnus Harlander Mail: har...@harlan.de Web: www.harlan.de Stiftung: www.harlander-stiftung.de Ceterum censeo bitcoin esse delendam!
