How to Install CMailServer and Web Email Server

1. Download the latest version from our web site and run the setup program. CMailServer will be configured automatically at the first launch.
2. If CMailServer reports "Fail to start SMTP or POP3 service", it means another program is using the same port of CMailServer. CMailServer will report which program is using the port and try to stop it.
3. If CMailServer reports "Set web share folder failed", it means the system doesn't install IIS service. Please read "Requirements" and follow the instruction to install IIS.
4. Check Webmail.
Open http://127.0.0.1/mail in IE at server.
1) If cannot open it, please check if IIS service has been installed.
2) If IIS service has been installed, you need to check the security properties of folder db, webmaildownload and webmailupload. To edit folders' security properties, please open folder's properties, go to "security" tab, allow "everyone" to read and write.
3) If "-ERR connect pop3 server failed" is reported, it means the firewall software on the server blocks the access of Webmail to CMailServer. You need to add CMailServer to the firewall software's white list or exceptions.
4. For more questions please refer to FAQs on our web site.

How to Install Internet Email Server

CMailServer configuration

1. Install CMailServer on an Internet dedicated server with static Internet IP address.
2. Open "Options" of CMailServer.
3. Select "Run as Internet Mail Server".
4. Suppose you have an Internet domain "topmail.com". Then fill "topmail.com" to the "Mail Domain Name".
5. Contact your domain's administrator or domain service provider and set MX record as your Internet server address.

Mail account configuration

There are two methods to create mail account.

Method 1: On CMailServer's user interface, select menu "Account" and then click "Create new account".
Method 2: Visit http://192.168.0.1/mail/ in IE and click "Sign up now".

Email client software settings

SMTP server address: 192.168.0.1
POP3 server address: 192.168.0.1
The outgoing mail server requires authentication.

How to Install Dynamic Domain Email Server

Dynamic domains are a new technology growing with the expansion of ADSL.
Due to the fact that ADSL doesn't provide static IP addressing, users who want to set up an Internet email server using ADSL, need to do following:
1. Register a legal Internet domain name.
2. Apply for an account from an ISP, for example, dns2go.com. Usually the ISP will provide you with a client application. Install this application on your server. You will need your ISP to modify the MX record direct mail to your server.
3. The rest of the steps are the same as those of how to install an Internet email server.

How to Install Dial-up Email Server

Before configuring LAN/dial-up mail server, we'd like to introduce some some background information about it.

Most companies don't have an Internet dedicated server. But most of them have a server with dial-up or ADSL connection. They have their own email address provided by ISP. But the ISP email service has some limitations such as:
1) Local email need to be transferred via Internet.
2) It's difficult to manage mail account and backup emails.
3) All clients need to access Internet to retrieve and send messages.
LAN/Dial-up mail server can solve all above problems.

All messages will be sent to CMailServer first, then CMailServer will send them to Internet. At the same time, CMailServer downloads all the Internet emails using multiple threads. The clients don't need to access Internet at all.

CMailServer configuration

1. Make sure the server can access Internet and install CMailServer on the server. Suppose the server address is 192.168.0.1.
2. Define a virtual domain (example topmail.com. Also can be a company owned Internet domain).
3. In "options" of CMailServer, select "Run as LAN/Dial-up mail server" and set "topmail.com" in domain name.


Mail account configuration

CMailServer provides two methods to create mail account.

Method 1: On CMailServer's user interface, select menu "Account" and then click "Create new account".
Method 2: Visit http://192.168.0.1/mail/ in IE and click "Sign up now".

When sign up mail account, you need to input an Internet mail address (respond to "Contact email address" in account property), POP3 server address, account and password of this Internet mail address. When CMailServer receives email from client, it will auto replace the "from" with this Internet mail address in account property, so the mail receiver can reply email to this Internet mail address. At the same time, CMailServer will use the POP3 information to download Internet emails.

Email client software settings

SMTP server address: 192.168.0.1
POP3 server address: 192.168.0.1
The outgoing mail server requires authentication.

How to Install LAN Email Server

Server configuration

Open "options" in CMailServer.
1. Select "run as LAN mail server"
2. Fill "topmail.com" in "domain name"

How to Install Multiple Domain Names Email Server

Most settings are the same as single domain mail server, except -

In "options" of CMailServer, select "multiple domain" and set multi-domain information with "add", "edit" and "delete" button.

The account for sign-up and login should be the whole email address.
For example: email address: user@topmail.com. The login account is "user" in single domain mail server and it's "user@topmail.com" in multi-domain mail server.

To configurate CMailServer as multi-domain mail server, you need to change all domain's MX records to your server address.

Webmail service

Suppose the server address is 192.168.0.1. You can access Webmail with "http://192.168.0.1/mail/" in web browser.

Mail proxy configuration

CMailServer provides mail proxy server and you can use this service to send or receive external email account. You can active it by select "mail proxy" in "options".

Suppose -

External email address: support@youngzsoft.com
Login Account: support
External SMTP server address: smtp.youngzsoft.com
External POP3 server address: pop3.youngzsoft.com

CMailServer address: 192.168.0.1

In email client, you can use following settings to retrieve and send emails with external email account -

Login account: support#pop3.youngzsoft.com
SMTP server address: 192.168.0.1
POP3 server address: 192.168.0.1
Outgoing server settings: Account is "support#smtp.youngzsoft.com" (if the external outgoing server doesn't require authentication, you should set account here as "#smtp.youngzsoft.com").
