which email service does identities ?
 

In an effort to spoof online identity when registering for various services/forums online and also spoof advertising cross referencing based on email header contents, I'm in the market for an email service providing a number (let's say more then 30) of identities/aliases on their own domain name(s).

The provider needs to:
- not use third parties services to run their email service (such as outsourced anti spam)
- strip sender IP from smtp client email sent
- not have a recurring unique identifier other then the identity/alias in the full header
- not share or sell any user related data to third party companies

Runbox does not have it as of yet, perhaps in the future.
fastmail claims they have but share user data with third parties.
Polaris claims they have it but only on 1 domain
mailfence claim they have it but only on 1 domain

Who else would you recommend?

I think Hushmail comes close.
