Those are just comments.  "dnl" means Delete through NewLine,
i.e. ignore everything up to (and including) the next newline
character.

That means that milter-greylist did not start.  You either
had an error in the configuration file, or some permission
problem, or a directory did not exist, or similar.

OK, so the reason was that the directory didn't exist.

Big mistake.  You cannot touch a socket, because it will
create a plain file, not a socket (wouldn't make any sense
anyway).  You must delete  that file, then start milter-
greylist.  The socket will be created automatically when
milter-greylist performs a listen() call (which is the
_only_ way to properly create a socket file).

Because sendmail doesn't seem to check the type of the
file (plain vs. socket).  That might be a bug in sendmail.

Not surprising.  There's no socket, so sendmail cannot
communicate with milter-greylist.  (Probably the milter-
greylist process wasn't running at all because of the
previous error condition.)

It logs where you configured it to log.  :-)
For me, it's in the standard mail log (/var/log/maillog).

That's non-default.  Maybe the person who created the
package that you installed modified it.  In that case
it should be documented somewhere in your package.

That's the default location.

"python" is more likely to pass unharmed through your spelling
checker than "perl".
