Hey 👋

Yea, default SMTP ports like 25 are blocked by default on new accounts to prevent abuse. Even though you’re using authenticated Gmail SMTP, the block still applies.

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

Your best bet is to either:

  • Reach out to DigitalOcean support and ask if they can review your account and unblock it (they don’t always do it, but worth a try),

  • Or use a service like https://smtpfa.st/, SendGrid, Mailgun, or Postmark, much better for deliverability anyway. They allow SMTP over API, which is a good workaround and better for performance too.

Some SMTP providers like https://smtpfa.st/ also support alternative ports like 2525, so you might want to check if Gmail does (last I checked, it doesn’t, but maybe worth double-checking).

Let me know how it goes!

Hope that this helps!
