According to the SunOS 4.1 System & Network Administration manual, page 746,
the $=m class is a special class set to the domain name of this host.

Well, pardon me if I'm wrong, but isn't the domain name a singular value?
Shouldn't it therefore be a macro, not a class?  How is this class created,
exactly, and exactly what does it hold?  (I don't have sources.)  Is there a
debugging value that shows the definition of all macros and/or classes?

While I'm at it, I have a second question regarding hostnames.  The $w macro
is set to the hostname of this site.  For some sendmails, this is always the
short name, even if the hostname as reported by gethostbyname() contains the
domain.  For other sendmails, the entire hostname is stored.  This is an
annoying discrepancy between various sendmails...

In any case, the $=w class is supposed to be a special class set to all of
the names this host is known by.  Where does this information come from, and
for newer sendmails for which class tokens can contain dots, does this
include the domain name or not?  The same question abotu a debugging value
applies as above...

Thanks in advance.
