You have a common precedence issue. Change the following line.
open FILE, $filename || die $!;
to
open FILE, $filename or die $!;
or if you really want to use ||
open(FILE,$filename) || die $!;
also it wouldn't hurt to be more verbose:
die "Could not open $filename: $!\n";
UPDATE: The usage of the \g modifier is for multiple matching,substituting,etc. you don't need it if you know what you are searching for only occurs once as is the case:

The original value of $from is "--from me@mydomain.com \"

EXAMPLE:
$str ='abcd'; $str =~s/a//g; # \g unnecessary ## $str = 'abacad'; $str =~s/a//g; # more appropriate
It wouldn't hurt to also have a look at perlop
