You will have to edit your sendmail's .m4 file to remove the
support for IPv6 (sendmail has been told to listen to ipv6 and
must be told otherwise) then regenerate the config file. We
don't edit /bin/ls to make changes; we don't edit sendmail.cf
to make changes. Change the source for those files and
regenerate them.
