As sendmail evolves,
it will continue to add new abilities to the qf
file. To protect old versions of sendmail from
wrongly misinterpreting new configuration files, the
V line has been introduced. Note that prior to
V8.7 sendmail there was no V
line. The V line, and qf
fileversion numbers for more modern
implementations of sendmail, are shown in Table 11-8.

If the version found in a qf file is greater
than that currently supported by sendmail, the
following error will be printed if in verbose mode:
Version number in qf (bad) greater than max (max)
and the following message will be logged:
Losing qf file unsupported queue file version
The bad qf file will then be turned into a
Qf file (marked as lost).
