<p><code>docker-mailserver</code> can serve as a relay too, but the difference between a DIY relay and a professional service is reputation, which is referenced by MTAs you're delivering to such as Outlook, Gmail or others(perhaps another <code>docker-mailserver</code> server!), when deciding if email should be marked as junked or potentially not delivered at all. As a service like SendGrid has a reputation to maintain, relay is restricted to registered users who must authenticate(even on port 25), they do not store email, merely forward it to another MTA which could be delivered on a different port like 25.</p> <p><code>docker-mailserver</code> can serve as a relay too, but the difference between a DIY relay and a professional service is reputation, which is referenced by MTAs you're delivering to such as Outlook, Gmail or others(perhaps another <code>docker-mailserver</code> server!), when deciding if email should be marked as junked or potentially not delivered at all.

If both client and server support <code>STARTTLS</code> the connection will be secured over TLS, otherwise the connection is unable to use encryption to secure it. By default, <code>docker-mailserver</code> is configured to reject connections that fail to establish a secure connection when authentication is required, rather than allow an insecure connection (<em>Port 25 will allow receiving unencrypted deliveries which doesn't require authentication</em>).</p>
<p>Support for <code>STARTTLS</code> is not always implemented correctly, which can lead to leaking credentials(client sending too early) prior to a TLS connection being established. Third-parties such as some ISPs have also been known to intercept the <code>STARTTLS</code> exchange, modifying network traffic to prevent establishing a secure connection.</p> <p>Support for <code>STARTTLS</code> is not always implemented correctly, which can lead to leaking credentials(client sending too early) prior to a TLS connection being established.
