HOW TO COMPILE SENDMAIL 8.11 FOR MILTER SUPPORT WITHOUT THREADS
Sendmail 8.12 comes with milter support out of the box. Sendmail 8.11 isn't
so fortunate, as milters were still in development in that version.
Typically, compiling Sendmail 8.11 with milter support requires building
libmilter (which requires pthreads). However, libmilter is not required by
PMilter, so it's useful to compile Sendmail 8.11 with milter support in the
daemon, but without the libmilter add-on.
To do this, add the following to devtools/Site/site.config.m4 (taken from
libmilter/README). Note that this does *not* include adding -D_FFR_MILTER
to "conf_libmilter_ENVDEF":
dnl Milter
APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_MILTER=1')
This will allow compiling Sendmail with milter support. However, if the OS
does not have a working <pthread.h>, compilation may fail. To fix this,
apply the following diff, which will prevent inclusion of <pthread.h> during
compilation.
