While testing, both of these suggestions worked great. I grew suspicious and decided to test the original configuration, and it worked too. Inexplicably, the issue has gone away. I reverted back to the previous server setting (imap.zoho.com), and the issue is gone from that server as well. I'd like to think it was my support ticket that did the trick, but likely not. In any case, I've added alerting on failure to my systemd script so that in the future I will know immediately when this happens.
