550-Verification failed - allowing bogus sender domains

I've got an internal server that needs to send a notification to an external email address. So the sending email address is [email protected] for example. internal.local of course does not exist publicly. I prefer not spoof a different return address. I have a third party spam filter service that all the incoming email goes through. I whitelisted this address so it goes through.

I am wondering if you can force the domain verification off?

When I think about it, seems it's probably better not to do so and just change the from address on the notification to a legit domain but I'm still curious.
