You can continue to add email accounts to your new mail domain, but your initial configuration is not completed yet. Before adding more accounts to your mail server, I would definitely finish the configuration first for proper testing.
- In the left window tree, expand the Settings section to reveal SMTP and select it.
- Click the Delivery of Email tab and populate the Host Name with the address of your WHS. It is essential that this be completed so that the mail server knows its public name.
Some ISP’s actually restrict access to certain ports and most that do also restrict access to port 25. Luckily for me, this isn’t the case; if you fall into this category, you still have some options.
Before you test whether or not your mailserver is functioning, you MUST add it to your firewall exceptions list and forward the ports (Default Ports = TCP – 25, 110, 143) in your router if you are using one. Adding the application to the windows firewall is extremely simple. You can access the firewall configuration by opening the Windows Firewall application in your control panel.
- In the Exceptions tab, select add program
- Navigate to c:\Program Files\hMailServer\Bin
- Select hMailSErver.exe.
- Click OK a few times and you now have allowed hMailServer as an exception in your Windows Firewall.
To determine if your ISP blocks access to port 25 open a command prompt and type: telnet xxxxxx.homeserver.com 25 (where xxxxx.homeserver.com is your WHS address). If you can connect, you are golden… if not. You have more work to do.
One of your options is to have your ISP’s mail server act as a relay for your home mail server. In the same section you specified your SMTP hostname, you will see an option for an SMTP relayer. This is the information you will need to populate to have your ISP’s mailserver act as a relay for you. Fill in the SMTP relayer field with your ISP’s mail server information: mine would be smtp.comcast.net and provide your credentials for accessing your email in the fields below.
