This applies to Windows servers that are not running Plesk.
By default, a Windows server will not allow incoming connections for POP3 and SMTP. You will need to update the firewall to allow connections on the required ports.
To update the firewall:
- Go to Start
 - Run ‘Windows Firewall with Advanced Security’
 - Click ‘Inbound Rules’
 - Click ‘New Rule’
 - Choose ‘Port’ as the rule type
 - Enter ‘110,25’ as the specific ports
 - Name the new rule
 - Click ‘Finish’
 
Once the firewall has been updated, you can then create the mailboxes.
To create a mailbox:
- Go to Start
 - Run ‘MailEnable Administrator’
 - Go to ‘Messaging Manager’
 - Click ‘Create Postoffice’
 - Enter the domain name as the name of the post office
 - Go to the newly created post office and click ‘Create Mailbox’
 - Enter the local part of the email address (the mailbox name)
 - Enter the password
 - Set a size limit
 - Click ‘OK’
 - The mailbox is now created
 
To connect to the mailbox you have created, use these settings:
Incoming POP3 Server: IP address of your server
 Port: 110
 SSL Encryption: Off
Outgoing SMTP Server: IP address of your server
 Port: 25
 SSL Encryption: Off
Username: The whole email address (mailboxname@postoffice)
 Password: As set when you created the mailbox
 Authentication Type: Plain Password Authentication
IMAP is not supported by MailEnable.
