Partial IPv6 support coming up on 2.99.47 ZMailer


( Cc: netdev@roxanne.nuclecu.unam.mx  -- Linux network code wizarding
  with interests also on IPv6 )

I started my local ZMailer smtpserver with options:  -a6s ve -l smtp.log
and this is what it reported, when I telneted to the local port:

00000#  started server pid 5599 at Tue, 18 Mar 1997 20:42:12 +0200
5602#   connection from IDENT-NONSENSE@[ipv6.::ffff:] (port 40736)
5602w   220 mea.tmt.tele.fi ZMailer Server 2.99.47 #1 ESMTP+IDENT ready at Tue, 
18 Mar 1997 20:42:22 +0200
5602#   remote from [ipv6.::ffff:]
5602r   quit
5602w   221 2.0.0 mea.tmt.tele.fi Out

Interestingly the server does listen on IPv6 port, but it will transparently
map back to IPv4 services at the same machine.

Now to figure out when to query for IPv6 AAAA -records from the DNS, and
when to use plain ordinary A-records so that the SMTP client can do its
tricks properly.
(Oh yes, using IP-address-literal trick I can already send to an "IPv6"
 address, but it is kludgeish:   nobody@[ipv6.::ffff:] )

... and somebody needs to define IPv6 version of the ident (aka "auth")
