The ino is the inode number for the df file. In our lost+found
example, the following command could be run to pair up the orphaned files:
% grep "^I.*/.*/" *
#1200:I123/45/3124
#1325:I123/45/1528
This shows that the qf file #1200 has the df file #3124 and that the qf file #1325 has the
df file #1528.
The sendmail program does not check the inode number in the I line against the actual
inode number of the df file. Instead, the I line is generated afresheachtime the qf file is
processed.
When df, qf, and xf subdirectories are used, and when those subdirectories are on separate
disks, a crash of one disk can leave the df or qf file intact, and the other in lost+found.

11.12.10 K line
The time last processed from the queue V8.7 and later
The MinQueueAge option (?§24.9.78 on page 1057) sets the length of time a queued message
must remain queued before delivery can again be tried. Eachtime sendmail processes a qf
file, it subtracts the time stored in the K line from the current time and compares the result
to the MinQueueAge. If sufficient time has not passed, the rest of the processing is skipped.
(Note that this test is performed only if the qf file has been processed at least once; see the
N line in ?§11.
