Allow a company to change the email@example.com to something similar to no-reply@<companyname>.com.
Allow a company to change the firstname.lastname@example.org to something similar to no-reply@<companyname>.com. This allows for a more specific whitelisting/trusting and prevent legitimate SharePoint share requests from being quarantined. Currently the only option is to create a transport rule to bypass spam filtering for all email@example.com (according to Microsoft ticket).

This is a major security consideration. I am disappointed that Microsoft di not realize the problems this causes. Whitelisting and blacklist is messed up, when all sharepointonline uses the same from address globally.
My users are not getting their email, and I cannot tell them to whitelist because security will not let me. I am in a catch-22, that should have been foreseen.
This is a potential security flaw that allows phishing emails through any gateway protection in place as well as the emails passing through O365's own filters.
Please address this, Microsoft.

This idea has also been posted several other times here recently. A few of those duplicates are:
Hopefully the UserVoice admins can consolidate all of those (and their votes) into a single idea!

At a minimum, ensure that emails coming from firstname.lastname@example.org pass SPF and DKIM validation. These emails are regularly going to spam with failed SPF records.

Because of the generic email address we are unable to differentiate messages from our clients. This makes automating message flows harder than it should be.
