&mailoff;

This syntax calls the named sub using the same @_ array as currently exists -- which doesn't since you aren't in a subroutine. Is that what you intended or are you just using the & calling style? (It is an older style held over from Perl 4 and generally not necessary unless you actually want to reuse @_.)

From reading the way your code is structured, it doesn't look like you're familiar with subroutine parameters. I think you might want to read perlsub, which talks about how subroutines pass arguments.

Here's some typical ways of passing and returning values:

sub some_function {
  my $arg1 = shift;         # shift the first value off of @_
  my ($arg2, $arg3, ) = @_; # or copy all of @_ at once

  # process stuff

  return $some_value;
}

# called like this
$value = some_function( 1, 2, 3 );

For your problem, you probably want to store the result of IP_check and pass it to mailoff like this: mailoff( $ip_check_result ). mailoff will then need to shift the argument off of @_ as in the example above.

There are some other issues in your code around repeating my $info2, etc. -- you might want to also try use warnings as a learning tool
