If you have Net::DNS lying around this is a snap to write:

#! /usr/local/bin/perl -w

use strict;

use Net::DNS;
my $dns = new Net::DNS::Resolver;

for my $domain( @ARGV ) {
    my $mx = $dns->query( $domain, 'MX' );

    print "$domain\n";
    foreach my $rr ($mx->answer) {
        print "\t", $rr->exchange, ' (', $rr->preference, ")\n";
    }
}
__END__

output:
