Heya,
Checking the logs, you can see the following errors after some messages:
:25: Connection timed out
port 25 is closed for external use. There are a few ways to go about the problem
- try using ports like 465 or 587 for SMTP
- use a third party solution only for your E-mails. Good examples are sendgrid.
To expand more on blocking port 25 for new accounts, this is something DigitalOcean has been doing to reduce spam on it’s network. It is more that we simply cannot accurately determine who is going to send it.
Stopping spam is a constant fight, so DigitalOcean has implemented some restrictions on newer accounts. Having said that, you can always contact them and ask for the port block to be lifted on:

Hope that helps!
