recently, I regularly get error mails from postfix because somebody registered with an email address of a non-functional mail domain.

such domains could end up on a blacklist and account registration could be rejected for them.

If we what to do that I suggest to create a separate project as this could be helpful for others to. I'm not sure how effective this approach is, as these trash mails providers (and their domains) come and go frequently.

it could be also like a regular check: if a user account has an email address/domain on the blacklist, it will trigger a similar "get rid of this" mechanism as when you don't use a host for a long time.

i get tons of mailer daemon spam meanwhile due to people using non-working email addresses.
