1.1     ! root        1: Greetings,
        !             2: 
        !             3:        To run sendmail with the name server you must:
        !             4: 
        !             5:        1) rebuild sendmail with the -lresolv
        !             6:        2) rewrite the configuration files
        !             7: 
        !             8:        The -lresolv selects the gethostby* calls that
        !             9: utilize the name server and resolver.  The module that
        !            10: uses the gethostby* calls is daemon.c.  An example
        !            11: Makefile is src/Makefile.ns.
        !            12:        The directory nscf contains example configuration
        !            13: files for interfacing with the name server.  A new right
        !            14: hand side syntax has been added - $[ and $].  Anything
        !            15: enclosed between the two is passed to maphostname in
        !            16: daemon.c to be resolved by the name server via the
        !            17: gethostbyname().  For example the ruleset:
        !            18: 
        !            19: R$+<@$-.ARPA>  $@$1<@$[$2.ARPA$]>
        !            20: 
        !            21: when passed [email protected] will pass host.ARPA to the
        !            22: name server for qualification.  This might return
        !            23: host.berkeley.edu if this were host@ARPA's fully
        !            24: qualified name.  For additional information about the
        !            25: name server and resolver see the man pages.
