in reply to Removing data from a string with Regex

In true TMTOWTDI style you could also use that which is below, although it is lacking a bit in the optimization.
$from =~ /@/; $from = $`;

    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
