We have a requirement to send automated emails to another monitoring system. We wanted to use watcher for this but unfortunately that second system cannot handle multi-part emails, only text/plain emails. I know its a stretch that xpack supports this, but I've looked through the configuration of cluster email settings and watch email action settings and i'm not seeing anything that will send a non-multi-part plain-text email. Is there any way to achieve this with the current implementation of xpack?
Our watch action does not supply a body.html, only a body.text and no attachments.
