Installation of CMailServer
Basic Requirements
1. Hardware: CPU P166+, Hard disk 1G+, RAM 128M+.
2. OS system platform: Win2000/WinXP/Win2003. If you want to use
web mail, IIS service is required.
3. If installed firewall, please open port 25 and 110. CMailServer
will use these two ports to transfer mails.
How to install IIS
Open Control Panel->Add/Remove Programs -> Add/Remove Windows
Components -> select Internet Information Service
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
It is used for LAN or Intranet mail communication. Suppose the
server address is 192.168.0.1 and domain name is "topmail.com".
Server configuration
Open "options" in CMailServer.
1. Select "run as LAN mail server"
2. Fill "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".
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 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").
