I haven't really kept track of which remailers are how reliable; they're almost all relatively new and experimental, people are hacking software, they go up and down a lot, and I almost never use them anyway. I also don't like keeping track of the syntax and which ::'s are followed by which ##s :-) Julf's anon.penet.fi remailer is serious; he's done a lot of work to get a private machine, payng for a reasonably expensive 64kbps line himself, and has it located somewhere that only 3 people know. (The original was located at a university, and somebody decided they wanted it Closed.) It's also outside the US, which is useful, . On the other hand, it works differently than the one-way anonymous remailers, uses up a substantial fraction of the net.bandwidth into FInland, and costs him real bucks - somebody ought to start a US equivalent and deload him. I'd guess tht extropia is also probably well-run, or at least has good features. But I haven't used it.
