Defining MATCHGECOS causes code to be
included inside sendmail for support of limited
fuzzy name matching. This process is described
under the MatchGECOS option (MatchGECOS). This MATCHGECOS compile-time macro is
normally defined as true by default. If you want to turn it off, use
an expression such as this in your Build
m4 file:
APPENDDEF(`conf_sendmail_ENVDEF', `-DMATCHGECOS=0 ')
disable fuzzy name matching inside sendmail
If you are running a precompiled sendmail
binary, you can use the -d0.1 debugging
command-line switch (-d0.1) to determine if
MATCHGECOS support is included (if it appears in the list, support is
included).
