Create a folder for this <?=strtolower($evaluationType)?> named <b class="copyText"><?=$evaluationName?></b> and keep all documents used for <?=$evaluationType?> <?=$evaluationNumber?> in that folder.
<ol start="1" class="count">
<!-- 1 -->
<li>Create a directory called <b><?=$evaluationName?></b>. We will use it for all work performed in this lab.</li>
<!-- 2 -->
<li>Install Postfix Mail Transfer Agent (MTA).
<ol>
<li>Install Postfix as per <i> <a href="https://ubuntu.com/server/docs/mail-postfix">Install and configure Postfix</a> and by reviewing the recordings.</li>
<li>Configure Postfix to utilize the <b class="copyText">~/Maildir</b> directory for email. <span class="normal note">See <a href="https://help.ubuntu.com/community/PostfixBasicSetupHowto#Setting_Postfix_Support_for_Maildir-style_Mailboxes">Setting Postfix Support for Maildir-style Mailboxes</a>.</span></li>
<li> I also set <b>myhostname</b> as <code class="copyText nowrap">myhostname = <?=$domain?></code> and added my network to the <b>mynetworks</b> setting: <code class="copyText nowrap"><b>mynetworks</b> = your_network_and_slash_mask, 127.0.0.0/8</code>. These settings are in your <b>/etc/postfix/main.cf</b> file.
<span class="normal note">Change <b>your_network_and_slash_mask</b> to the network ip and slash mask of your server. Start with the ip address of your server and change the last octet to 0 and add <code>/24</code>. This will give you something like: <b>192.168.56.0/24</b>.</span></li>
<li>Restart the Postfix service.</li>
<li>You can test your installation by searching for "Telnet SMTP example" and following the example or watch the recording.</li>
</ol>
</li>
<!-- 3 -->
<li>Install Dovecot Mail Delivery Agent (MDA).
<ol>
<li>Install Dovecot Server as per <a href="https://https://ubuntu.com/server/docs/mail-dovecot">Install and configure Dovecot</a> and by reviewing the recordings.</li>
<li>Configure Dovecot to utilize the <b class="copyText">~/Maildir</b> directory for mail. This setting is in the <b>10-mail.conf</b> file. See <a href="https://help.ubuntu.com/community/Dovecot#Choice_of_Mailboxes">Choice of Mailboxes</a>.</li>
<li>Configure Dovecot log paths with <code class="copyText nowrap">log_path = /var/log/dovecot.log</code> and <code class="copyText nowrap">info_log_path = /var/log/dovecot-info.log</code>. These settings are in the <b>10-logging.conf</b> file.</li>
<li>Configure Dovecot authentication with
<code class="copyText nowrap">disable_plaintext_auth = no</code> and
<code class="copyText nowrap">auth_mechanisms = plain</code>.
These settings are in the <b>10-auth.conf</b> file.</li>
<li>Configure Dovecot trusted networks with <code class="copyText nowrap">login_trusted_networks - your_network_and_mask</code>. This setting is in the <b>dovecot.conf</b> file.
<span class="normal note">Change <b>your_network_and_mask</b> to the slash network of your server. Start with the ip address of your server and change the last octet to 0 and add <code>/24</code>. This will give you something like: <b>192.168.56.0/24</b>.</span>
</li>
<li>Restart the Dovecot service.</li>
<li>You can test your installation by searching for "Telnet IMAP example".</li>
</ol>
</li>
<!-- 4 -->
<li>Ensure both your <b><?=$Uusername?></b> and <b><?=$username2?></b> accounts exist on your Ubuntu server.
<ol>
<li>Open a terminal and enter <kbd class="copyText">cat /etc/passwd | grep "<?=$Uusername?>"</kbd>.
<br>You should get a response like: <kbd><span style="color:red;"><?=$Uusername?></span>:x:1000:1000:<?=$userFullname?>:/home/<span style="color:red;"><?=$Uusername?></span>:bin/bash</kbd>.
<br>If you do not you need to create the <b><?=$Uusername?></b> user.
</li>
<li>In the terminal, enter <kbd class="copyText">cat /etc/passwd | grep "<?=$username2?>"</kbd>.
<br>You should get a response like: <kbd><span style="color:red;"><?=$username2?></span>:x:1001:1001:,,,:/home/<span style="color:red;"><?=$username2?></span>:bin/bash</kbd>.
<br>If you do not you need to create the <b><?=$username2?></b> user.
</li>
</ol>
</li>
<!-- 5 -->
<li>Install the <b>Thunderbird</b> client software and send an email. <span class="note">You will use your <b>Windows 10 VM</b> for this step of the lab. You also need the <b><?=$Uusername?></b> and <b><?=$username2?></b> users on your <b>Windows 10 VM</b>.</span>
<ol>
<li>Login as your <b><?=$Uusername?></b> user.</li>
<li>Download and install the <b>Thunderbird</b> client software.</li>

<br><span class="note">For Postfix errors look in the <b>mail.err</b>, <b>mail.log</b>, <b>mail.info</b>, and <b>syslog</b> files.
For Dovecot errors look in the <b>dovecot.log</b>, <b>dovecot-info.log</b>, and <b>syslog</b> files.
If you see errors mentioning that Dovecot cannot mkdir Maildir subfolders you should do: <kbd class="copyText nowrap">sudo chmod 755 /var/lib/dovecot</kbd>.</span>
