[OCCAID] rDNS request ..

[Suresh Ramasubramanian]

OK - got a box with v6 up and running, occaid /48

ifconfig gif0 tunnel 204.74.68.40 204.152.184.210
ifconfig gif0 inet6 2001:4830:e0::2 prefixlen 64 up
route add -inet6 default 2001:4830:e0::1
ifconfig lo0 inet6 2001:4830:20b0:b::2 prefixlen 48 alias
ifconfig lo0 inet6 2001:4830:20b0:b::3 prefixlen 48 alias

2001:4830:20b0:b::2 and 2001:4830:20b0:b::3 do have proper rDNS as
frodo.hserus.net and smtp-out.hserus.net, and are my regular mailhosts

Only problem - v6 packets go out over the tunnel's interface
2001:4830:e0::2 and that's the source IP that's visible to any v6
mailserver that receives email. That doesnt have rDNS set, and I've got
to email a guy like Vixie who wants rDNS on any email that he gets :)

  paul at vix.com
    SMTP error from remote mail server after RCPT TO:<paul at vix.com>:
    host sa.vix.com [2001:4f8:3:bb::1]: 550 Client host rejected:
    cannot find your hostname, [2001:4830:e0::2]

Any idea how to either

1. Get rDNS for the e0::2 IP

or

2. Set packets to go out through smtp-out.hserus.net and make that the
source IP that's visible.
