The problem of spam filtering is so bad that most IP addresses are presumed guilty even if they have no prior spam history, such as if their network or subnetwork had spam issues in the past.
That's overstated. That applies to consumer Internet connections. But it's not hard to find professional server hosting that is not blacklisted. It's also very easy to use third parties like authsmtp to handle IP reputation.
