I could write a procmail recipe and a script in about an hour to automatically secret-share-split and redistribute the incoming submission. If the authorities attempt to indict you for possessing illegal information / kiddie porn / whatnot, they have to prove that you interfered with the automatic redistribution process and examined the contents of the submission. If you in fact did not look at the submission, they would have a difficult time doing so.

The problem with a procmail script, unlike the ugly on-the-fly SMTP-like splitting method I proposed, is that the suspicious message is in your mail system, intact, and if they nail you before you can dispose of it, they can prove you had it. (Even though procmail does stuff quickly, sendmail still accumulates the material before delivering it, doesn't it?) They still have to prove that there's something illegal or forfeiture-supporting about the way you possessed the message, but by then you're hauled into court and your computer is stolen. The Feds argued in the Steve Jackson Games fiasco that intercepting unread mail in mailboxes is different than intercepting it in transit, and while we can hope that will be overturned, it's better not to be the guinea pig. If your machine never has more than a few bits of the message, they can't catch you in possession of the message - they can only argue that bits of it flowed through your machine, and that's much harder to build a case on, and given the abuse the judge gave the Bad Guys in the SJG case, it's probably easy to prevent them from keeping your machine as evidence, or at least get it back. Your paranoia may vary.... Bill
