As I understand your question, you want to send an e-mail if the file times are all larger than 1 hour. If this is incorrect, I apologize and please respond with clarification.

One solution would be to set a flag if a new file is found and test that flag after the loop, like: 

     my $new_file = 0;
     for $file ($ftp->ls){
             push @files, $file;
     }

     for $file (@files) {
       $localtimenoformat=time;
       $mdtmnoformat=$ftp->mdtm($file);

        unless ( ($localtimenoformat - $mdtmnoformat) > 3600 ) {
           print "$file";
           print "Localtime No Format =  $localtimenoformat";
           print "MDTM      No Format =  $mdtmnoformat\n";
           $new_file = 1;
        }
     }
     envia_mail() unless $new_file;
     $ftp->quit or die $ftp->message;
