Looking for some best practices, 


1. Is there any way to set up Microsoft Team "Channel" email addresses to use * instead of



2. We are experiencing ALOT of emails getting caught as phishing (AntiPhishPolicy) or SPAM from the  and  sender addresses for some reason in EOP/EOL and security is not wanting to whitelist those domains.

No. As explained in the documentation/blog articles, Teams uses a special tenant for handling the email to channel functionality, and we have no control over it. You can however create a mail contact for the generated address and assign it a alias.
