Trace switched map finds Debug command-line switch
A switched map is one that, either as the result of a service-switch file or because of sendmail’s internal logic, causes lookups to follow a select path. For example, Sun’s Solaris 2 nsswitch.conf might specify that aliases be looked up in the order files, then nis:
switch_map_open(name, file, mode) ← from -d38.2 switch_map_find => nummaps dbtype ...

printed, such as files, or nis.
