540 | Chapter 15: Debug sendmail with -d
??? Beginning withV8.13 sendmail, th e-d switchmay no longer be combined with
the -q switch. This prevents direct tracing of the queueing process:
WARNING: Cannot use -d with -q. Disabling debugging.
15.7 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 witha 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.
