This is a pretty confusing question because it has nothing to do with DMARC, SPF, or DKIM, and "same company" reads like "consistent spammer". I think what you're getting at is the use of a local address in the author display name: > From: User <u...@company.com> <arte.fin...@creativegroup.com.ec> > To: other.u...@company.com Did you actually mean that precise form, which looks invalid, or did you mean one of: From: "User <u...@company.com>" <arte.fin...@creativegroup.com.ec> From: User <u...@company.com>, <arte.fin...@creativegroup.com.ec>
