Re: Blocking Inbound Email Domains

[Jeremy Livingston <jlivings () STEVENS EDU>]

We see very few legitimate emails from those domains, so have made the decision to add them to our "Quarantine" list.  
Users can review this weekly and whitelist legitimate emails they receive.

Has anyone made the decision to block inbound emails from domain such as protonmail.com, onionmail.org and if so any 
negative consequences or pushback in doing so?

Thanks,
