Whoer.net sees some proxies as blacklisted. What can I do about it?

Even Whoer says the blacklists do influence SMTP messaging. Very many mobile and residential proxies have been blacklisted. This happens when a single external ‘white’ IP address is shared by hundreds of devices, some of which may be infected and sending out SMTP spam; the address may end up in a blacklist. This concerns SMTP messaging only, other functions are not affected.
