NodeMailer plus Apple Mail -- how to create a Draft email

Question

Trying to use NodeMailer to create a Draft email in Apple Mail.

The following approaches have not yet been successful:

• Using NodeMailer's mail option saveToDrafts: true
• Saving an email as a .eml file in the Finder, using AppleScript to open the file and convert it to a Draft (Note: Creating and opening in Apple Mail works just fine, but the result is a read-only, unsendable email that must be converted manually to a Draft using Apple Mails "Move to..." button. Trying to get rid of that manual step.

Answer 1

NodeJS package imapflow's append can be used to push an .eml file (created, say, by nodemailer's mailcomposer).
