My Droplet IP 64.227.174.118 can connect outbound to Gmail MX on port 25, but Gmail rejects mail with:
550 5.7.1 The IP you’re using to send mail is not authorized to send email directly to our servers.
Can DigitalOcean confirm whether this IP range is suitable for direct outbound SMTP, or recommend the approved SMTP relay path?

Hey,
The SMTP ports (25, 465, and 587) are blocked on all Droplets for new accounts to prevent spam and other abuses:
You could reach out to the DigitalOcean support team and check if they could lift the block for you but in many cases this is not possible:
Another option here is to use a service like https://smtpfa.st/ or SendGrid or another SMTP service that use a non-standard SMTP port like 2525 for example. Also going for SMTP over API is a good option here.
Heya, @meetbhanushali
You can open a support ticket and request the SMTP restriction to be lifted on your Droplet and they’ll usually do it if your account has some history and you explain the use case.
- 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.
