A REST API for IMAP
Having a built-in REST API for IMAP, either similar to or compatible with the Gmail API would be amazing, especially if you could limit user rights in Plesk so that you could have domain specific access, or read-only access etc. The imapapi linked to nodemailer is a huge step forward but integration with Plesk would be ideal since security is paramount for an API that can access mail. Obviously this is a long-term request.
