I used the Ansible playbook instructions and got my instance up and running, which is where I’m sending this from now. Still, I was not able to get the SMTP side of things working. Does this whole setup self-host SMTP on the Lemmy instance, or is it something I’ll have to sort out externally? I’ve heard some people have had issues with Digital Ocean on certain ports, which is the VPS provider I’m hosting on, but even other ports I’ve tried have not worked.
Yep. DigitalOcean specifically recommends SendGrid as an alternative: https://docs.digitalocean.com/support/why-is-smtp-blocked/
