SOCKETMAP

Enable use of socket database-map type (V8.13 and above) Tune with confMAPDEF

The SOCKETMAP compile-time macro enables use of the new socket database-map type (Alphabetized Database-Map Types). You define SOCKETMAP inside your Build m4 file with a line like this:

APPENDDEF(`confMAPDEF', `-DSOCKETMAP')

If you use a vendor-supplied sendmail program, you may check to see whether it includes SOCKETMAP support by running a command like the following:

% /usr/sbin/sendmail -bt -d0.4 < /dev/null | grep SOCKETMAP

If a line of text containing SOCKETMAP is printed in response, you indeed have support for SOCKETMAP. If not, you will either need to contact your vender or download and build open source sendmail.
