If your domain is hosted here at Pulsant and you would like to have your mail delivered directly to your server from anywhere on the internet then you simply need to email [email protected] from an authorised address requesting the change.
We will need to know your domain name, the IP address of your mail server and whether or not you would like us to act as secondary back up for any brief periods that your server may be unavailable.
Note that in order for us to configure this method of delivery Pulsant needs to host your domain DNS. Please see the section on Domain Name Hosting for information on how to order this.
If your mailserver is behind a Pulsant ADSL broadband connection then you will need to request that we open port 25 for you. If you have a routed subnet (static IP addresses) and your mailserver is using one of these then you should request that we open port 25 on this IP. Otherwise we would open port 25 on the WAN IP address of your ADSL connection. If you are behind a Pulsant SDSL or leased line connection then port 25 will already be open on our firewalls.
IMPORTANT – when requesting port 25 opened on your ADSL connection you need to clearly state in your email to us that you intend to keep the mailserver online at all times, fully patched and updated at all times and that it will not be configured as an open relay.
Once we receive the request we will change the Primary MX (Mail eXchange) record on the DNS for your domain so that all mail servers on the internet will attempt to connect directly to your server to deliver mail.
