Reference for -d in Numerical Order

The sendmail debugging switches vary from vendor to vendor and from version to version. This section is specific to V8.14 sendmail. These switches are perhaps best used with a copy of the sendmail source by your side. Be further advised that many of the internal details shown here will change as sendmail continues to evolve and improve.

In Table 15-4, we provide a detailed description of categories that we consider useful for the system administrator who is trying to solve an email problem. Categories that are of interest only to sendmail developers are omitted. If you need to use a category not listed here, you must examine the source and find a category that will solve your unusual problem.
