Re: exim relay and ipv6

[Andrew Pounce <adp@ntohs.co.uk>]

Have you made sure that you have a relay_hosts line something like....

relay_hosts 127.0.0.1 : <ip.v4.add.ress> : ::::1/128

Note that as :'s are used as field markers you need to double them up
like :-

  nnnn::nnnn::nnnn::nnnn::nnnn::nnnn/64

Cheers,
