I want to grep for errors in the file before the transmission starts ... If I find errors, I'll move the file to another directory so it can't be sent. ... is there another way to search a file all at once before I open it in the above code to start the send process?

Since you need to open the file before grepping it, try something like 

      open FILE, "$senddir/$file"
          or die "$senddir/$file: $!"

      my $file = do { local $/; <FILE> };
      close(FILE);

      if ( $file =~ m/$errors/mo ) {
          # move the file
      } else {
          # open the socket and send $file, as before
      }
  }

where $errors is a regular expression that you set up in advance with the patterns that mean "error" to you. (Or, you can hard-code it). The /m on the regex allows you to use ^ and $ to match lines within $file.
