I can't see my error here Monks!!!

I just need to grep where data from the pattern file exists in the input file.

input.file looks like this :
David@domain.com|David@domain.com|J|ABBASS, DAVID JOHN|
Cory@domain.com|Cory@domain.com|E|ABBOTT, CORY J|
Tania@domain.com|Tania@domain.com|F|ABBOTT, TANIA LEE|
Geoffrey@domain.com|Geoffrey@domain.com|N|ABBOTT, GEOFFREY BRYAN|

pattern.file looks like this :
Randall@domain.com
David@domain.com
Rob@domain.com
Tania@domain.com

Script should tell me that Tania@ and David@ exist :

sub main {
 my $filename = "input.file";
 open (my $valuesFile, '<', 'pattern.file')  or die "Failed: $!\n";

while (<$valuesFile>) { push (@lines, $_); }
 open(INPUT, $filename) or die "Cannot open $filename";
  while (<INPUT>) {
   ($userName,$emailAddress,$division,$fullName)  = split(/\|/, $_);
    while (@lines) {
     my $pattern = pop @lines;
     $pattern=~s/\n//g;
     #print "pattern: ".$pattern."address: ".$emailAddress."\n";
     if ($emailAddress =~ /$pattern/) {
      print $pattern . "  exists in " . $emailAddress."\n";
     } else {
      print $pattern . "  no match  " . $emailAddress."\n";
      last;
    }
  }
}
close(INPUT);
close $valuesFile;
}
