Filter disposable email addresses without violating privacy policy

Seems to be not programming question, but sooner or later every (web) developer will face it, so I strongly believe it fits to stackoverflow, because zillions of developers must find a usable answer to this, and also should solve the existing solutions privacy related issues.

I find many service and API in the web what offers validate an email address against its (internal) disposable email domain list. I think using this method is a very bad idea. Practically all today's web sites ensure its users it have very trustable privacy policy, and never, never exposes the users email to a 3rd party. Now using this emerging "disposable email validation services" what is your first thing: expose your users email to a 3rd party. It maybe just the domain name, but still, it is definitely hurts privacy, and surely against your sites privacy policy.

I understand if one has an up to date list of a disposable email domains that's a value which one do not want to expose, but still the community have free and updated lists for similar situations.

I've found some public list, but neither seems to be updated (see links below)

Do anyone know a publicly available list, which is updated regularly?
