Not that I have any idea how I'm supposed to run scripting on the backend yet (working with support to get info on this), but is there any info I've missed on sending emails from custom plugins or other software running on the server? I could do SMTP myself but it would be nice to leverage the existing configuration present for the SMTP service instead of having more duplicate configuration somewhere else.
At the moment, we don't have any documentation available to allow you to use the SMTP service however I can see how that would be useful. I'll make sure that we consider this for future releases. Thank you for the feedback!
