Two Unix to Perl questions about my Perl on Unix scripts:

I want to convert the following line in my Perl script to Perl instead of using the Unix system command. 
system("cat $file | mailx -s 'Title' emailaddresshere");

I tried but doenst want to work: 
open(FILE, "$file");

while (<FILE>)
{
        print | mailx -s 'Title' myemailaddresshere;
}

My next system question: I have the open STDERR, "/dev/null" in beginning of my script but still get an output from this in my script. Anyway to redirect this Unix system output to /dev/null area so I do not see the output on my screen?? 
system("/usr/sbin/ping $_");
