is it possible to use this as a util?

[hulkish]

As opposed to running a full fledged SMTP server... is it possible to use this as a util to just sent an email - from say just a scripting perspective?

For example, php has.a.way of sending emails via a mail() function - without needing to setup any SMTP server. Is that possible with haraka? If so, please point me in the right direction.

Yes, but you should likely be using nodemailer instead.
