Recommended for anyone TBH as I've taken it way beyond the standard setup.
I just need a GitLab.com ID from anyone wanting access. I've not made it public as I wouldn't have time to keep up with those obligations yet.
It is all "production ready", and used on 3 live instances now. But I'm also evolving it fast, so anyone wanting to use in production would just need to get familiar with it first so they know what to expect is already done and what is still to do.
Someone from the EspoCRM Forum discoverd that i need to enable smtp auth. With this i can send mails.
Background for not enabling smtp auth:
We use Office365 as Mail System. Because we run some Apps in our cloudron i marked the Server as trusted host in the office365 exchange system. With this all the apps can send Mails without entering Mail Server data.
Topic is solved for me.
