Ahh... I'm sure we have some older clients that are still configured to use a different hostname...

So, if the new certs are for mail.example.com, and a client tries to connect using a different hostname, like imap.example.com, would that result in these kinds of errors?

yes

and that is why nobody should provide more than one hostname for mailservers there is no gain and it ends where you are now

would you have not wasted the time for different DNS records instead just provide and communicate mail.your-primardy-domain.tld all the years before TLS now would be a no-brainer
