+ <h2>Configuring User E-mail Address</h2>
|
|
|
+
|
|
|
+<ol>
|
|
|
+ <li>In a web browser, navigate to the Proxmox web UI and login</li>
|
|
|
+ <li>Select Datacenter > Permissions > Users from the left navigation menus</li>
|
|
|
+ <li>Double click the user to configure</li>
|
|
|
+ <li>Complete the E-mail field on the Edit User form > Click OK</li>
|
|
|
+</ol>
|
|
|
+
|
|
|
+<h2>Simple Configuration via Web UI</h2>
|
|
|
+
|
|
|
+<p>By default, Proxmox will try to use the domain portion of the "Email from address" as the e-mail relay server.</p>
|
|
|
+
|
|
|
+<ol>
|
|
|
+ <li>Select Datacenter > Options from the left navigation menus</li>
|
|
|
+ <li>Double click the Email from address field</li>
|
|
|
+ <li>Enter the e-mail address that Proxmox will send outgoing e-mails from > Click OK</li>
|
|
|
+ <li>Expand Datacenter > Select the node name > Click Shell in the left navigation menus</li>
|
|
|
+ <li>Run the following commands in the terminal
|
|
|
+ <div class="codeBlock CMD"># send a basic test email<br />
|
|
|
+ echo "Test email from Proxmox: $(hostname)" | /usr/bin/pvemailforward<br />
|
|
|
+ # output the mail log<br />
|
|
|
+ cat /var/log/mail.log</div>
|
|
|
+ </li>
|
|
|
+ <li>Notice the relay is the domain (i12bretro.local) from the Email from address setting</li>
|
|
|
+</ol>
|
|
|
+
|
|
|
+<h2>Advanced Configuration via CLI</h2>
|
|
|
+
|
|
|
+<p>To make more advanced configuration changes, like using a gmail account, you need to edit the postfix settings via command line </p>
|
|
|
+
|
|
|
+<ol>
|
|
|
+ <li>Back in the Proxmox web shell, run the following commands in the terminal
|
|
|
+ <div class="codeBlock CMD"># install libsasl<br />
|
|
|
+ apt install libsasl2-modules -y<br />
|
|
|
+ # edit the postfix config<br />
|
|
|
+ nano /etc/postfix/main.cf</div>
|
|
|
+ </li>
|
|
|
+ <li>Press CTRL+W and search for mydestination</li>
|
|
|
+ <li>Comment out mydestination by adding a # to the beginning of the line</li>
|
|
|
+ <li>Press CTRL+W and search for relayhost</li>
|
|
|
+ <li>Comment out relayhost by adding a # to the beginning of the line</li>
|
|
|
+ <li>Update or add the following configuration
|
|
|
+ <p>relayhost = smtp.gmail.com:587<br />
|
|
|
+ smtp_use_tls = yes<br />
|
|
|
+ smtp_sasl_auth_enable = yes<br />
|
|
|
+ smtp_sasl_security_options =<br />
|
|
|
+ smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd<br />
|
|
|
+ smtp_tls_CAfile = /etc/ssl/certs/Entrust_Root_Certification_Authority.pem</p>
|
|
|
+ </li>
|
|
|
