Installing and configuring MailEnable


Guide to installing and configuring MailEnable. Includes basic pre and post installation requirements.


Configuring the environment
Before installing MailEnable, ensure that the environment has been configured correctly. This includes configuring network connectivity and the public DNS Server. MailEnable should be configured in an environment with a static IP address but (although not recommended) can be configured to work in environments with dynamic IP addresses using products like DynDNS or dns2go, etc.

1. Before installing MailEnable, ensure that the machine can access the Internet (i.e.: ping Ensure that other computers can ping the server's IP address from the Internet (technically computers do not need to be able to ping the server, but they will need to be able to connect to TCP/IP ports 110 and 25 of the server). In most cases, this requires some firewall configuration. You will need to allow the following ports through your firewall, depending on the services you are running. If you have configured MailEnable to listen or send on other ports, you will of course need to permit these through the firewall.

Service Port Inbound Outbound
POP 110 allow allow
SMTP 25 allow allow
IMAP 143 allow deny
LDAP 389 allow deny
HTTPMail 8080 allow deny
Webmail 80 allow deny

2. Ensure that the correct entries are registered in the DNS. The first step to doing this is to determine who has control of your public DNS records. Contact your ISP or DNS provider to determine who holds the records for the domain. This will allow you to determine who can create new DNS records for the domain. When hosting mail for a domain, each domain being hosted requires a number of DNS records to be created. The DNS records that need to be created are listed here: Article ME020048

It is important to understand the role of DNS and how it relates to running mail servers. This is outlined in the following Knowledge Base article:   Article ME020190

Installing the MailEnable software
Now that the environment is configured, MailEnable can be installed. The product manuals explain how to install MailEnable.  These are installed with the product or available from our website here:
