zmailer under ultrix

[Matthew Newhook <matthew@engr.mun.ca>]

I figured out the problem after... it was caused by my defining of
PUNT_HOST to the same host that the zmailer was running on.  This
caused address lookups to loop, and bad things happened from there.
Perhaps this should be mentioned in the INSTALL file?
