[Question] How to get email working on Lemmy-Ansible install?

I used the ansible method to install Lemmy on a DigitalOcean VPS. They do block port 25 and there is no way around that. I tried to change the port from 25 to 465 in the config.hjson file but still no luck. I am super new to this but I want to get this working so bad. I’m so close! The site is working fine, just no emails....
