4.35: Sendmail

<ftp://ftp.sendmail.org/sendmail/>

If you want to use SRC to start and stop BSD sendmail,  do the following 
after installing it:

chssys -s sendmail -S -n 15 -f 9 -a -d99.100

This tells SRC that sendmail may be stopped with signals 15 and 9.  It also
arranges for sendmail not to daemonize itself,  since it will run under SRC.
