sendmail, 4th Edition

The -d0.1 (a.k.a. -d0 ) debugging switch previously prevented sendmail from forking and detaching itself, but that function has been moved to the -d99.100 debugging switch. The -d0.1 debugging switch now just tells sendmail to print information about its version:

Version 8.12.7 Compiled with: LOG MATCHGECOS NAMED_BIND NDBM NEWDB NETINET NETUNIX NIS = == == == == == = SYSTEM IDENTITY (after readcf) = == == = (short domain name) $w = here (canonical domain name) $j = here.US.EDU (subdomain name) $m = US.EDU (node name) $k = here = == == == == == == == == == == == == == == == == == == =

The Version is the current version of sendmail . Note that for Sun the number can look like SMI-8.7.5 or 8.12.3+Sun .

The Compiled with : lists the compile-time definitions that were specified when sendmail was compiled. All the available definitions are listed in Table 3-2 in Section 3.2.

The SYSTEM IDENTITY shows the value assigned to four important macros. The meaning of each macro is shown in Table 21-7 in Section 21.9.
