Thanks for taking time to read this post.

We acquired a new domain for a new company service.

I've successfully added the alias to accounts that all accounts that require it and tested to verify I can receive/send messages via the alias.

However, when testing with my personal gmail, I see "user@aliasdomain.com via primarydomain.com" in the from field.

What is the best course of action I can take to suppress this message?
