Sounds like something has given you an IPv6 routed address, without
actually giving you IPv6 routing. Exim should try the IPv4 addresses
too and succeed. What's the error when it tries the IPv4 addresses?
You can set "disable_ipv6" in the main section of the configuration to
tell Exim to avoid doing anything with IPv6, while you fix whatever's
wrong with the host setup.
