Back references are used in the "match" side of a s/// regexp not the
"replace" side, in that case you should use $1, $2, etc..

If I run a script such as:

#!/usr/bin/perl
use strict;
use warnings;

my $foo = "username";
$foo =~ s/^([\w\-\+]+)$/\1\@mycompany\.com/; 
print $foo . "\n"'

I get the output:

username at mycompany.com

but I also get a warning:

\1 better written as $1 at -e line 1.


I hope that helps,
