A more typical perl routine wouldn't attempt to read the entire inbox
in one fell swoop into memory.  This can cause bizaar memory problem
(I've seen it before on my Mac, but never my .5gig Ultra2 sparcstaton)
I.e. (OK, I also threw in a slight mod on how I handle looking for
specific things by using next.  Oh, and one more thing, you probably
didn't really mean to look for "From:" inside a message, but "^From:"):

#!perl -w

$inPath = "test y";
$outPath = "test x";
$file=0;  #init my file count

open (MAIL, $inPath) || die "can't open: $!";
open (MAILOUT, ">$outPath$file.html") || die "can't open: $!";
while (<MAIL>) {
      chomp;
      next unless /^From:/;
      $file++;
      $auther[$file] = $_;
      print STDOUT "this is $auther[$file] and the file is $outPath$file\nand this is the @auther\n\n";
}
close (MAIL) || die "can't close  MAIL: $!";
close (MAILOUT) || die "can't close  MAILOUT: $!";
