You're going to get a lot of false positives if you do this because if
there's a server problem in verification of the sebder it's going to bounce.
I wonder if there is a way to distinguish a DNS error from a domain that
doesn't exist?
5xx on nonexistent sender domain requires NXDOMAIN to be returned for that
domain. If there's a temporary error - say SERVFAIL, it'd be a 4xx error.
The sending MTA can retry later and if the dns resolution fixes itself /
gets fixed, email will get through just fine
