That's what port 587 is for.

Why? Mail servers can be reasonably expected to require some kind of authorization to accept mail on port 587. So that port is useless for spammers, unless they can hijack your credentials. And if they can, at least the blame can be placed on your business, where it belongs. Your business will then likely lock your account until your machine can be cleaned.
