What this means for your email list
Is a free-provider address a problem?
Addresses at post.com are legitimate and deliverable in general. What goes wrong is the mailbox part before the @: typos, old accounts and abandoned inboxes. That is what per-address verification catches.
Sender authentication
post.com uses a DMARC quarantine policy: mail that fails authentication is sent to spam. That is a sound middle step, and a good sign the owner looks after their email setup.
