[Mesh] DNS free email

[Stuart Gathman]

The folks on SSB are excited to discover that with the permanent
authenticated cjdns IPs, you can fairly easily dispense with DNS for
sending and receiving email.  In addition to enabling raw ips on my
gathman.org server, I installed opensmtpd on a node behind NAT, and can
send and receive emails with no registration anywhere.

I would post a link, but the gateway for the "corporate web" is down. 
If you are on SSB, check out the #email channel.

To give you the idea, you can email me at
stuart@[IPv6:fcd9:7f8a:e050:4b48:7fd6:7fa:5509:6e26]

I just added [IPv6:fcd9:7f8a:e050:4b48:7fd6:7fa:5509:6e26] to
/etc/mail/local-host-names to make sendmail accept mail for that domain.
