When such a joined line is later used
(as in a header), the joined line is split at the newline and prints as two separate lines
again.
16.5 The V Configuration Command
The V configuration command was added to V8 sendmail to prevent old versions of
configuration files from breaking when used with V8 sendmail. The syntax for the V
configuration command looks like this:
Vlevel ?†? V8.1 through V8.5
Vlevel/vendor ?†? V8.6 and above
We describe the level and vendor parts in the next two sections.
16.5.1 The V Configuration Command??™s Level Part
The level is a positive integer. If level is higher than the maximum allowed for the
current version, sendmail prints the following warning and accepts the value:
Warning: .cf version level (lev) exceeds sendmail version ver functionality (max)
If level is less than 0 or if the V configuration command is omitted, the default level
is 0.
The effects of the various version levels are relatively minor. As sendmail continues to
develop, they might become more pronounced. Currently, the version levels are as
follows:
0
The check for a valid shell in /etc/shells is ignored (?§4.8.3 on page 180).
0 through 1
MX records are looked up withth e RES_DEFNAMES and RES_DNSRCH cleared. The
high bit is always stripped from the body of every mail message.
