The class $=P holds a list of pseudodomains that will not be looked up using DNS.
Unless you use a FEATURE(), this class will contain a dot only. Various FEATURE()s will
add appropriate pseudodomains to it, such as .UUCP and .REDIRECT.
The class $={src} (prior to V8.13) or $=Src (V8.13 and later) holds a list of rule set
names that can be called to look up items in the access database. It is a clever trick
that you might wish to copy for use in your own rule sets. To see how this trick is
performed, look for that expression in your configuration file.
22.4 Internal Class Macros
Prior to V8 sendmail, only the class $=w was used internally, and only a small handful
of classes were used in the configuration file. Recently, more and more classes have
been added to that list. Table 22-3 lists all the class macros defined internally by
sendmail as of V8.14.
