Can I set-up an email server or is port 25 blocked by default?
I am working on several projects, one of which is automating the setup of an email server. Testing this script out on Amazon Web Services is difficult since port 25 is blocked by default - the only workaround is using a 3rd party such as Google or Mailgun to send the emails on my behalf. I am wondering if there is a way to do this on Digital Ocean or if port 25 is also blocked by default?
