I have a legitimate email today from @example.onmicrosoft.com (both
envelope sender and From: header) that is a cross-organisation meeting
invite. Normally all of their email uses their domain but some
Microsoft
software is using this internal domain for meeting invites.
Indiscriminate blocking is going to unexpectedly reject real email.
There are some very well-known major corporations who have had policies
of rejecting any meeting invites with .ics files unless the sender is
whitelisted. Too many people do not expect random strangers "inviting"
them to meetings and have their settings configured to auto-accept
invites.
