      <description>&lt;p&gt;An SMTP server is used for delivery of email notifications, reports, and other communications from Dynatrace to users and administrators.&lt;/p&gt;

Configuring an SMTP server connection is optional but highly recommended.  
* If you decide not to configure your own SMTP server, [Mission Control](/support/help/setup-and-configuration/dynatrace-managed/operation/how-does-mission-control-pro-active-support-work/) will deliver your email for you. However, you will have to make sure that your network connection is stable. If your Dynatrace cluster is unable to connect to Mission Control and you have no SMTP server configured, email notifications won&apos;t be delivered and you may not be notified of important problems with your cluster.  
* Configuring your own SMTP server offers you full control over where and how your email notifications are sent out.  

&lt;/div&gt;


--&gt;
&lt;p&gt;To configure an SMTP server connection&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Log into the Cluster Management Console and select &lt;strong&gt;Settings&lt;/strong&gt; from the menu.&lt;/li&gt;
&lt;li&gt;Expand &lt;strong&gt;Emails&lt;/strong&gt; and select &lt;strong&gt;SMTP server&lt;/strong&gt; to display the &lt;strong&gt;Configure SMTP server&lt;/strong&gt; page.&lt;/li&gt;
&lt;li&gt;Set &lt;strong&gt;Connection security&lt;/strong&gt; to the security protocol you want to use for your SMTP server.&lt;br&gt;
The default is &lt;code&gt;No encryption&lt;/code&gt; on port &lt;code&gt;25&lt;/code&gt;. If you change &lt;strong&gt;Connection security&lt;/strong&gt;, &lt;strong&gt;Port&lt;/strong&gt; automatically resets to match the standard port number for that protocol. If you manually change the &lt;strong&gt;Port&lt;/strong&gt; number however, changing the &lt;strong&gt;Connection security&lt;/strong&gt; protocol won&amp;apos;t reset the &lt;strong&gt;Port&lt;/strong&gt; number.
&lt;ul&gt;
&lt;li&gt;&lt;code&gt;No encryption&lt;/code&gt;: Not secure. Default port: &lt;code&gt;25&lt;/code&gt;.&lt;br&gt;
With &lt;code&gt;No encryption&lt;/code&gt; selected, email is sent unencrypted. Use this option only if the SMTP server supports no other option.&lt;/li&gt;
&lt;li&gt;&lt;code&gt;SSL/TLS&lt;/code&gt;: Secure. Default port: &lt;code&gt;465&lt;/code&gt;.&lt;br&gt;
With &lt;code&gt;SSL/TLS&lt;/code&gt; selected, email notifications will be sent out only when an SSL/TLS connection can be established.&lt;/li&gt;
&lt;li&gt;&lt;code&gt;STARTTLS optional&lt;/code&gt;: Not secure. Default port: &lt;code&gt;587&lt;/code&gt;.&lt;br&gt;
With &lt;code&gt;STARTTLS optional&lt;/code&gt; selected, once a STARTTLS connection is established, email is encrypted and sent out using STARTTLS. If a STARTTLS connection can&amp;apos;t be established, email notifications will be sent out without encryption.&lt;/li&gt;
&lt;li&gt;&lt;code&gt;STARTTLS required&lt;/code&gt;: Secure. Default port: &lt;code&gt;587&lt;/code&gt;.&lt;br&gt;
With &lt;code&gt;STARTTLS required&lt;/code&gt; selected, once a STARTTLS connection is established, email is encrypted and sent out using STARTTLS. If a STARTTLS connection can&amp;apos;t be established, email notifications will not be sent out.&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;Set &lt;strong&gt;Mail server&lt;/strong&gt; to the address of the SMTP mail server.&lt;/li&gt;
&lt;li&gt;Set &lt;strong&gt;Port&lt;/strong&gt; to the port number of the SMTP mail server. See &lt;strong&gt;Connection security&lt;/strong&gt; above for related details.&lt;/li&gt;
&lt;li&gt;Set &lt;strong&gt;Username&lt;/strong&gt; and &lt;strong&gt;Password&lt;/strong&gt; if the server requires authentication.&lt;/li&gt;
&lt;li&gt;Set &lt;strong&gt;Sender email address&lt;/strong&gt; to the address that should be displayed as the sender&amp;apos;s email address.&lt;/li&gt;
&lt;li&gt;Set &lt;strong&gt;Email test address&lt;/strong&gt; to the address where you want to send test messages.&lt;/li&gt;
&lt;li&gt;Click the &lt;strong&gt;Send test message&lt;/strong&gt; button to check whether your SMTP configuration works. Once you&amp;apos;ve sent a test message, check the inbox of the account specified in &lt;strong&gt;Email test address&lt;/strong&gt; field to see whether or not your configuration works.&lt;/li&gt;
&lt;/ol&gt;
