The trailing dot is even required in some contexts because it bypasses 
the configured search path.  For example, on some systems, "to" and 
"to." return different address records, and for some applications, the 
difference is rather important.

(This applies only to non-Windows systems, Windows has its own 
idiosyncrasies when it comes to the trailing dot.)
