Hi all,

I'm trying to courier-mta to work properly for me on a NetBSD 1.6 machine
(actually an SGI Challenge S, but that's hopefully not important right
now) within an IPv6 (6Bone) environment (so --with-ipv6 - turning it off
is not a realistic long-term option).

Everything compiles and installs and local delivery works fine.  However,
it doesn't seem to be able to send mail to remote MTAs.

I've given it an IPv6 DNS server to play with (it refused to use the IPv4
servers that were available).  That got it trying to talk SMTP/IPv6 to
those of my mailservers that have IPv6 addresses (but unfortunately,
delivery fails because those machines don't talk SMTP/IPv6... yet... the
reason I'm playing with courier-mta, actually).

But it won't even attempt a connection to IPv4-only MX hosts, which kind
of foils my evil plan for world domination...er... I mean IPv6 sweetness
and light, with peace in our time... ;)

Is this because it's trying to make IPv4 connections from IPv6 sockets?
Can we make this work somehow?  It seems to me that a fallback to IPv4
operation would be handy (including IPv4 MX entries for dual-stack hosts
would be useful too, in case they don't have SMTP/IPv6 support).

Thanks in advance for any help,
