SmarterMail 14.x Help

IP Addresses

System administrators can use this section to specify on which ports the IPs on the server should listen. All ports being used should be assigned to at least one IP. However, SmarterMail provides system administrators with some flexibility when configuring IP bindings. This means, for example, that the system administrator can allow POP (port 110) on the IP 111.111.111.11 but not on the IP 222.222.222.22. In addition, some servers may have other programs installed that need to listen on mail ports. To accommodate this, the system administrator can configure SmarterMail to listen on a subset of IP addresses, leaving the remaining IP addresses available for other programs.

Another benefit to binding IPs to your mail server is that you can limit the possibility of your entire mail server being blacklisted by assigning IPs on a per domain basis. That means that spammers sending messages on your mail server will only get their domain and their specific IP blacklisted rather than getting the entire mail server blocked.

To access the IP address settings, click the Settings icon and expand the Bindings folder in the navigation pane. Then click IP Addresses. A list of IP addresses on the server will load in the content pane and the following options will be availble in the content pane toolbar:

  • Edit - Edits the ports assigned to the selected IP.

Note: The IP Addresses listed in this section are pulled from the server and can only be removed from SmarterMail by removing the IP Address from the Network Interface Card (NIC).
