I've been burned by this too. And this is a problem that will only get worse as the trend continues from actual e-mail clients to webmail. hotmail.com, live.com, webmail.aol.com, mail.google.com, yahoo.com; there are so many unknown IP addresses behind these few webmail domains that it is impractical to block them. _______________________________________________ tor-relays mailing list [email protected] https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays
