No outbound registration emails

[ericyu00]

I have a new Mastodon instance set up using Cloudron in a DigitalOcean droplet, and the site is running and I've got myself configured as admin, but when trying to register the first test user, the confirmation/registration email is not going out. Any suggestions how/where to trace this?

Never mind, after a bit of poking around it seems DigitalOcean does not allow for port 25 outbound (at least not that I could find), so needed to configure external SMTP service (via SendGrid). Maybe there's a better/cheaper way to do this, if anyone has guidance on that happy to take it!

@ericyu00 If you write to DO support, they usually open it up.
