Hi Henry
You have 2 options here:
[OPTION 1]
According to the bat book 3rd ed. you can invoke a ServiceSwitchFile
option to point host lookups to a file by doing one of the following:
O ServiceSwitchFile=<path> <--- .cf file
-OServiceSwitchFile=<path> <--- invoked from cmd line
define(`confSERVICE_SWITCH_FILE', <path> <--- in .mc config file
where <path> is the path to the service switch file containing
directives in the form of "<service> <how> <how>"
<service> can be "hosts" "aliases" or "passwd" - in this case you'd want
to enter "hosts". <how> can be "files" "nis" "netinfo" "nisplus" or "dns"
so to only look at a file for name lookups you'd specify in your service
switch file: "dns files"
where "files" refers to your nsswitch.conf file (already configured, I
hope).
[OPTION 2]
(I don't think you're original question indicates that the following is
what you're looking for, but I'll include the info anyway jic)
You don't even want DNS_BIND enabled in the binary? This'll fix it's wagon:
in your devtools/Site/site.config.m4 file (or whereever you put your
local build definitions), enter:
APPENDDEF(`confENVDEF', `-DNAMED_BIND=0')
and then recompile sendmail. I wouldn't recommend this unless you are
either not connected to the Internet at all or are running a UUCP box
(sheesh, do those even exist anymore?)
Anyway, hope this helps you out!
Regards,
Chuck
