I understand your reasons and got used to it. Still fun. :) > Disclaimer: I must say I have no clue what the current state of the > art is in the remailers field. I made a summary: https://sourceforge.net/p/whonix/wiki/Remailer/ (Mixminion is not listed there, but most remailers run Mixmaster, Cypherpunk and Mixminion at the same time. Since Mixminion isn't ready yet (there own statement) and Mixmaster has too few users, not too much has to be learned about remailers. > Is Mixmaster the best current solution? No. Refer to mixmaster as a tool to send mails. Ignore any mixmaster anonymity giving aspects. Anonymity is provided by Tor. And this is about running a mail sending tool over Tor. > How serious are the > known attacks? There are too few users. I consider it off topic here, but anyway, Roger Dingledine made very nice comparison: http://www.mail-archive.com/[email protected]/msg00022.html >> It's small. >> ~3 MB for postfix > > I like Postfix very much, and its security record is pretty good, but > I'm not sure a full blown MTA in Postfix' class is needed for this > usecase. Wouldn't e.g. msmtp-mta be enough? Perhaps Mixmaster can be convinced to talk to it. I don't know. Further implementations (Mixfaster, Mixminion) will not require an extra mailserver anymore. >> ~0,1 MB for Mixmaster >> guess ~1 MB for web frontend. > > Does the web frontend include a webserver in this ~1MB?

It is my understanding, that Mixmaster itself doesn't, but Postfix does. It looks like the standard way for an MTA to resolve the MX for a given mail server domain. I haven't found a way to disable it. I tried k54ids7luh523dbi.onion (remailer.frell.eu.org) or gbhpq7eihle4btsn.onion (snorky) as relayhost in /etc/postfix/main.cf, but still keep getting "status=deferred (Host or domain name not found. Name service error for name=gbhpq7eihle4btsn.onion type=MX: Host not found, try again)". > Can't we get rid of the need at the root? I don't know. Either getting the hidden mailservers to work, somehow deactivating need for it, patching the MTA (beyond my abilities) or... I really don't know. At the moment it's the biggest obstacle.
