Hey Greg,

One thing to note is that the SMTP ports (25, 465, 587) are blocked by default on DigitalOcean Droplets, which can cause issues with apps like Rocket.Chat if they’re trying to send email via SMTP:

https://docs.digitalocean.com/support/why-is-smtp-blocked/

Since you’re using SendGrid, the best option is to use SendGrid’s API instead of SMTP, that avoids port issues entirely. Make sure Rocket.Chat is configured to use SendGrid’s API key and endpoint, not SMTP.

You can also deploy SendGrid easily via the 1-Click App here:

https://marketplace.digitalocean.com/apps/sendgrid

If nothing works, best to reach out to the DigitalOcean support so they can take a closer look:

Heya, @gregpainter

SMTP is now disabled by default on all new accounts, meaning the SMTP ports will be blocked. To send mail from DigitalOcean, we recommend using SendGrid via the SendGrid Marketplace 1-Click App.

I’ve tried to check rocketchat docs for the email configuration to explore some other ways to deal with the issue but this leads to a 404 page now - https://docs.rocket.chat/docs/email-configuration
