How do I create a mailbox on my Windows server?

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:

1. Go to Start
2. Run ‘Windows Firewall with Advanced Security’
3. Click ‘Inbound Rules’
4. Click ‘New Rule’
5. Choose ‘Port’ as the rule type
6. Enter ‘110,25’ as the specific ports
7. Name the new rule
8. Click ‘Finish’

Once the firewall has been updated, you can then create the mailboxes.

To create a mailbox:

1. Go to Start
2. Run ‘MailEnable Administrator’
3. Go to ‘Messaging Manager’
4. Click ‘Create Postoffice’
5. Enter the domain name as the name of the post office
6. Go to the newly created post office and click ‘Create Mailbox’
7. Enter the local part of the email address (the mailbox name)
8. Enter the password
9. Set a size limit
10. Click ‘OK’
11. 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.
