The line number
in the warning is that of the line in the sendmail.cf file that began with the illegal
character.
An example of each kind of command is illustrated in the following sections.
1.8.2 The version Command
To prevent older versions of sendmail from breaking when reading new-style sendmail.
cf files, a V (for version) command was introduced beginning withV.1. The form
for the version command looks like this:
V10/Berkeley
The V must begin the line. The version number that follows must be 10 to enable all
the new features of V.14 sendmail.cf. The number 10 indicates that the syntax of the
sendmail.cf file has undergone 10 major changes over the years, the tenth being the
current and most recent. The meaning of each version is detailed in ?§16.5 on page
580.
The Berkeley tells sendmail that this is the pure open source version. Other vendor
names can appear here too. Sun, for example, would be listed on Sun Solaris platforms
and would cause the Sun Microsystems version of sendmail to recognize the
Sun configuration file extensions.
1.8.3 Comments
Comments help other people understand your configuration file. They can also
remind you about something you might have done months ago and forgotten. They
slow down sendmail by only the tiniest amount, so don??™t be afraid to use them. As
was mentioned earlier, when the # character begins a line in the sendmail.
