Configuring SMTPS in Virtualmin

by

0

Under System Settings > Server Templates (and under the dropdown menu “Edit template section”) > Mail client auto-configuration. In the section Thunderbird auto-configuration XML, under the heading outgoingServer, I changed the port from $SMTP_PORT to $SMTPS_Port and selected XMLtemplate below as opposed to Automatically generated. My XML template is therefore as follows:

<?xml version="1.0" encoding="UTF-8"?>

<clientConfig version="1.1">
<emailProvider id="$SMTP_DOMAIN">
<domain>$SMTP_DOMAIN</domain>
<displayName>$OWNER Email</displayName>
<displayShortName>$OWNER</displayShortName>
<incomingServer type="imap">
<hostname>$IMAP_HOST</hostname>
<port>$IMAP_PORT</port>
<socketType>$IMAP_TYPE</socketType>
<authentication>$IMAP_ENC</authentication>
<username>$SMTP_LOGIN</username>
</incomingServer>
<outgoingServer type="smtp">
<hostname>$SMTP_HOST</hostname>
<port>$SMTPS_PORT</port>
<socketType>$SMTP_TYPE</socketType>
<authentication>$SMTP_ENC</authentication>
<username>$SMTP_LOGIN</username>
</outgoingServer>
</emailProvider>
</clientConfig>

If the variable $SMTPS_Port doesn’t work for you, you can try manually entering port 465.

DNS Slave Using Virtualmin

DNS Slave Auto-Configuration Quickstart

A quick guide to assist administrators who want to use Virtualmin’s automatic DNS slave configuration features. This allows for DNS server redundancy.

Introduction

Virtualmin can automatically manage any number of DNS slave servers for you. Once configured, it will create slave zones on other servers and configure them to automatically update when changes are made on your Virtualmin server. For this to work, you need Virtualmin on your primary server and Webmin (a free download) on your slave server(s). Henceforth, all references will refer to the primary server as the “Virtualmin server” and the DNS slave server as the “slave server”.

Getting Webmin for the Slave

If you don’t have Virtualmin installed on your slave server(s), you’ll need to install Webmin. Webmin is available for nearly every UNIX and Linux variant available, and is free to download and use. Continue reading “DNS Slave Using Virtualmin” »

It’s pretty easy to build a Linux router even on a virutal machine. I’ve used virtualbox to create a LAN NAT router with DHCP services using webmin. However, I’m not going to cover on how to use a virtualbox VM 🙂

Let’s create the NAT Router first.

On Webmin go to Networking > Network Configuration > Routing and Gateways

Fig-1

  1. Select right ethernet interface on Default Route
  2. Fillup the correct gateway
  3. Enable “Act as a Router”

On Networking > Linux Firewall > Select “Reset Firewall” Continue reading “Create a Linux Router with DHCP services” »
