When it comes to email clients, DNS leaks and proxy bypassing are not the only concern. Email headers are a potent source of exposed private information, and are generally much less configurable by the end user - - and easily overlooked by less experienced users. The operator of mail.i2p/i2pmail.org (the email system inside I2P) compiled a list of popular email clients and compared them in the areas of anonymity and privacy protection. I don't know how current it is, but it does provide a good overview of how different clients expose different information within the email itself before the client even touches the network: http://hq.postman.i2p/?page_id=9 Incidentally, by postman's ratings, (Sylpheed) Claws comes out on top :) (For those without I2P I have pasted the page contents to http://pastebin.com/TDD5NzTn - postman doesn't allow access to his site via I2P inproxies) str4d -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQEcBAEBCgAGBQJSJonXAAoJENXeOJaUpGWy/cEH/ArZcUpNH5ZiqBnfxln/VNSK u7+I0t0NEkzcRLJxDrzvQMpJceOhhfufaHiox8ypxsww+ZjDZFThReXV3RSg+Oh4 Se+XIkuGdkYoqM6806SotdZz2idR9a9GRd1IeRzZBDqQI37q0KobirLl/0ucywOB +gWd0dTQhGIqj5LYrTdtLAdxQ559ydXLqGfWM2jpyeWbzog/ZpWTQtW7RF6MLCD1 RYlMqthqvKyX5wHvXm97g3GJWVGRJCAgYd4e5em7VBkKlEOM6tPcgPATo/xRFZJ4 vBqBHIQ6MXNpG5/VZgK1GI09XAysuXzbSS/ZVfWpY7m6/UBRpfG9eI4jMfmvoQs= =1N+0 -----END PGP SIGNATURE----- -- tor-talk mailing list - [email protected] To unsusbscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
