Each level includes the output
of all lower levels within a specified category.
??? The concept of debugging, versus other uses of -d, is muddled in sendmail. Tracing,
for example, can be valuable for tuning a configuration file, yet suchan
activity is not really debugging. We hope to make the distinction clear by documenting
only the ???useful??? debugging switches, and omitting the true code-level
debugging switches from this chapter.
??? Because the -d command-line switch shows details of the internals of sendmail,
the developers of sendmail consider that output to be unpublished material. As a
consequence, the details of debugging output documented here might differ
from what you see when running versions above or below V8.14. You are
strongly encouraged to avoid writing a program to parse debugging output
because such a program might become obsolete with a future release of sendmail.
