spamc/spamd using IPv6?

I just assigned AAAA records to my DNS, and spamc/spamd fails.

I have a DNS alias spamd for a server.

jarif@lancaster:~$ host spamd
spamd.fredriksson.dy.fi is an alias for lancaster.fredriksson.dy.fi.
lancaster.fredriksson.dy.fi has address 10.123.29.113
lancaster.fredriksson.dy.fi has IPv6 address fe80::20c:29ff:fe28:8af

Now my log is filled with

Jan 15 21:46:42 lancaster spamc[17968]: connect to spamd on
fe80::20c:29ff:fe28:8af failed, retrying (#16 of 100): Invalid argument

Any ideas?

However, it does depend on spamc being ipv6-ready, which means using
getaddrinfo() - I don't know if spamc does that.

The fe80: address is link-local, to use it you have to specify the
interface as well.  In a browser, you could do that like this:

http://[fe80::20c:29ff:fe28:8af%eth0]

You could try the same syntax with spamc - the %device is a glibc
extension, it might work.

Well,

You might want to start reading about IPv6 before you attempt to use it. 
  Just an idea ;)  Good on you for trying I guess.

And very off topic indeed; your ISP will in all likelyhood assign you 
with a mind-bogglingly huge amount of IP space, if you read the outline 
of IPv6 vs IPv4 you will soon realize this.

Good luck,

Chris

Link local is all I have ;) I know next to nothing about v6, but it is
coming... so testing things.

Off topic: I have currently one fixed IPv4 address, and several hosts
behind it with NAT. Do I need separate IPv6 addresses for each machine
later? Will the ISP provide them with please? I guess...

Hello,

Why use the link-local address?

Have a look at this thread;
