Project Combat: Emos Integrated mail system construction

Project requirements

Reform of Enterprise Mailbox system of XX company

-The original use of 263 enterprise mailbox, expensive (100 user version, 20,000/year), and the number of messages, size is limited.

--Other non-assigned enterprise mailbox employees use NetEase, Sina and other free mailbox, business communication there is a certain delay.

-With the company expanding, the number of employees has rapidly broken through to 300 people, the need for a consistent, low-cost mail system.

--The staff's computer level is different, in addition to support mail client, it is best to log in and send and receive mail through the Web.

Project analysis

Implementation Cost Considerations

---Abandon 263 enterprise mailbox, change to build mail system independently

--Acquisition of 1 PC servers (<5 million), deployed to the company room

Support for multiple mail domains

--The company already has domain name: tarena.com, 163.com

--Need to add MX record to domain Name service provider

Standalone mail server build

--based on Postfix, support virtual account (MySQL)

-Easy Web mailbox and service management platform

Project Environment Preparation

1. Optional server

2. Install and deploy the mail platform

3. Internal testing

4. Request an MX record from the service provider

5. Configure the corporate firewall, publish the mail server

6. Go online and test

7. Daily operation and Maintenance

Experimental Purpose: Install and deploy the mail platform

Lab Environment:

1.DNS server: IP address 192.168.1.20 host name: FANLJ Domain Name: nsd1.tarena.com

2.EMOS server: IP address 192.168.1.40 host name: mail.tarena.com Domain Name: mail.tarena.com

3.liunx Customer test machine: IP address 192.168.1.30 hostname: localhost

Mail management domain: @tarena. com @163.com

One. Prepare an available DNS server (centos6.5)
