sendmail, 4th Edition

Special Build-Time Support

You may either Build the libmilter library in its plain-vanilla form, or tune it to better support your environment. Table 26-2 lists the Build-time macros that tune the libmilter library. Note that some macros change the Milter library, whereas others change sendmail.
