This suggests there is no compiled-in default paths that it checks. If
no config info is loaded, the program is effectively a no-op.

...and you verified that /var/spool/mail/... (or the other variation) is
not in the binary, further confirming that there aren't compiled-in
default paths.

('strings', unlike strace, doesn't execute the binary, so what config
files are present is irrelevant.)

Give the logs you've shown, I suspect you are mistaken, as the code
doesn't even stat the spool file in the first scenario. It should have
no way of knowing if the file is empty, non-empty, or even if it exists.
The output message should be consistent in all 3 situations. You could
retest to confirm that, if you care. But I think you've resolved your
original problem, and we're just picking nits at this point.

(You might want to file a ticket against the Ubuntu package for
mailcheck suggesting that it should bundle an /etc/mailcheckrc with
reasonable defaults. If mailcheck ignores paths that don't exist, they
could list the few most common spool file/Maildir locations to cover
most of the bases.)
