Useful Tables

There are two tables of useful information in this chapter:

  • Table 16-1 lists all the -d categories in numerical order.

  • Table 16-2 lists only those -d catagories that are considered useful to the day-to-day management of sendmail.

Table of All -d Categories

In Table 16-1, we list all the debugging switches by category, regardless of their usefulness to the administrator, and give a brief description of each. If you need more detail about those we do not document, we suggest you use sendmail/TRACEFLAGS as a guide to the appropriate source code files.
