Yes, it is a solution to this problem. But for a single user. And how can you do it for the entire server?
If I may answer your question with a question: How well does "*our* entire (outgoing-)mailserver" translate to "for all e-mails our *users* send, including those working at remote locations or with mobile devices", assuming that that latter is your actual goal?
how does it matter where the user is and what device he uses?
the user *always must* use the one and only SMTP server responsible for his domain, especially in times of SPF, DKIM and DMARC and spoofing protections for incoming mail
anything else is an idiot ignoring the configuration data his mailprovider gave him supported by a second idiot running a MTA which allows random envelope-senders and in that case nobody but the user is responsible for rejected, dropped and lost mails
