Hello, @patrickbillings
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:
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:
