hubspot list of disposable domains

[johannesnagl]

i found that hubspot shares a list of domains they don't accept:

https://knowledge.hubspot.com/forms/what-domains-are-blocked-when-using-the-forms-email-domains-to-block-feature

there's at least "buerotiger.de" on it. would be nice if you could incorporate this list into your repo as well.

Note that list appears to be any free email provider (including gmail, iCloud, hotmail)
