Got a notification from the Zoho Mail UI about the new feature. Went looking for more info and found these:

- Thread from 2012 requesting PGP support, including responses pointing out the issues with entrusting one's private keys to a cloud provider: https://help.zoho.com/portal/en/community/topic/pgp-support-...

- Docs page for the new feature: https://www.zoho.com/mail/help/pgp.html

Can't help but raise an eyebrow at the docs' description of allowing Zoho to generate and control keypairs, though.
