BEWARE: Exim in potato.

[George Bonser <grep@shorelink.com>]

The Exim 3.02-1 is broken when run as a daemon. It works fine under tcp
wrappers.

If you run as a daemon it reads the config fine, forks off a child who
tries to bind to a socket but ends up with:

socket(PF_INET6, SOCK_STREAM, 0)  = -1 ENOSYS (Function not implemented)
socket(PF_INET6, SOCK_STREAM, 0)  = -1 ENOSYS (Function not implemented)
socket(PF_INET6, SOCK_STREAM, 0)  = -1 EINVAL (Invalid argument)

Then writes to paniclog:

1999-06-28 14:02:13 socket creation failed: Invalid argument

Stay away from this version of exim if you are running as a daemon!
