Using smtp2go with monit and cron?

[sarkyscouser]

Has anyone managed to successfully send emails via smtp2go from monit or cron?

I've had opnsense set up to send emails via google for a while but I'm trying to eliminate app passwords from my google account by implementing smtp2go.  I can send emails via smtp2go from linux command line, cron on my linux server and various dockerised services, but cannot get opensense to send emails from monit or cron, possibly because of the lack of a sender field.

I have smtp2go set up against my domain and it needs to verify user@domian.com as the sender to work in addition to smtp username and password, and most services have a sender field where I can enter this.  However in monit settings for example there isn't a sender field.
