	Gets host by addr

Attempts to cannonize name to primar 'A' record.  Name returned is not
cannonical.

Summary: DNS is misconfigured.


You are aware that you can not mix versions fo sendmail and bind and
changes in versions of FreeBSD networking structures, right?  You must
rebuild (a *matched*!) sendmail and bind if you update past a structure
change.  If you replace sendmail (or bind), you must generally replace
bind (or sendmail) at the same time.  This was especially problematic
when they were both "sanitized" for Linux style cshared library usage.
