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 with V.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
The V Configuration Command 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.
