Luckily the vast majority of IP's hitting spamtraps are end users/bots, so it would normally be quite rare to have a real actual mail server listed, however Gmail pushes this envelope to extreme, not so bad recently, but in the past, it has had a reputation almost as bad as the mid to late nineties AOL.
