Synopsis
The -d0.10 debugging switch causes
sendmail to print all the operating

OS Defines: HASFCHOWN HASFCHMOD HASFLOCK HASGETUSERSHELL
HASINITGROUPS HASLSTAT HASNICE HASRANDOM HASRRESVPORT
HASSETREUID HASSETSID HASSETVBUF HASUNAME HASWAITPID IDENTPROTO
IP_SRCROUTE SAFENFSPATHCONF USE_DOUBLE_FORK
Conf file: /etc/mail/submit.cf (default for MSP)
Conf file: /etc/mail/sendmail.cf (default for MTA)
