Use the 'last' command. See
http://www.perldoc.com/perl5.6/pod/func/last.html for an explanation of how
to use it. It works for breaking out of any loop e.g. foreach, while,
until.

I think you *can* just print stuff directly to sendmail. However, I found

quot;Can't open " strings, e.g.
insert 'print' or 'die' before them. You aren't putting the strings to
any use, therefore they are 'useless'. Does that make sense?
