It certainly matters to some extent. But you're right: It is not
(usually) just one thing that is an absolute yes/no issue. Matching
rDNS, SPF, DKIM, DMARC, good IP address history, TLS, use of IPv6 (and
of course not in blocklist and not in dynamic range), all count to
varying extents. The more you can do the better. Also, the larger your
non-spam, legitimate-content volume, the better your reputation (to the
extent that 'reputation' means anything).
