Publisher: NetBull Readings: 155 Tanghaijing (Submission) Chapter 4 Mail Server Section 1 Sendmail Server & 1.1 Introduction Mail Service is the most important network service that users need. The web has a large traffic, but the mail is mainly used in communication between individuals, and people - human communication is the foundation of business. The network without mail service is an incomplete network. In other words, if you cannot provide the user to provide mail support under the full TCP / IP, such a network operating system is not trustworthy. Configuring Sendmail is a big and complex work, but it is not entirely, and Linux has configured most of the settings compared to the case where other web server systems are installed, the SMTP server software is installed. Under the majority system, the default configuration can run well. I will give some suggestions for some configurations in this chapter. The main configuration parameters are recommended not to change at will. (LinuxByte Download Sendmail) & 1.2 Required Resources & 1.2.1 Required Package RedHat 6.2 Server Installation & 1.2.2 Required Profile /etc/sendmail.cf System Ossage, Administrator Configuration / Etc/sendmail.cw system comes with Administrator Configuration & 1.3 Configuration Scenario 1./etc/sendmail.cf Description: Sendmail The master configuration file controls the configuration of Sendmail runtime. Complete Sendmail Configuration should include 7 sections: local info (local information): This section defines the information option of the local host: Use to set options to define the Sendmail environment. Message Precedence: Sendmail Message Priority Trusted Users: Defines the user's Format of Headers that allows you to change the send address when you send an email: Define the message header information that is inserted in Sendmail ReWriting Rules. Rewinding rules): This part saves the rewritable email address command to use this command to rewrite the address form of the mail address from the address of the user mail program as the address of the mail sender. MAILER Definition: Defines the program that sends an email, the rewrite rule is the rule used by the mail, and is defined in this section.

2. Administrators need Touch / etc / mail / aliases and Touch / etc / mail / majordomo to create two files, then restart sendmail, generate two library files using sendmail.cf to generate two libraries: aliases.db And Majordomo.db; & 1.4 Test and Management Measures
& 1.4.1 Test Method
1. Administrators can make changes by executing /etmail restart by performing /etc/rc.d/init.d/sendmail restart
The configuration takes effect.
2. Administrators use not mail by performing fetchmail -u yourname yourserver
The user needs their password, and the user needs to be set according to the client.
3. Administrators should open the POP3 service, that is, change the configuration file
3. Administrators can perform Echo Test | / USR / SBIN / Sendmail on the server
- v thj@weboa.com.cn to test whether the created mail user can work properly.
& 1.5 small knot
In fact, we can implement the function of the Mail server as long as we set a few places, because Sendmail has strong applicability, and it is constantly updated. So now the SENDMAIL's configuration solution has been practiced, and there is no need to make too much changes to the administrator, you can achieve powerful SendMail features.
Section 2 QMAIL server
& 2.1 Introduction
Qmail is a new generation of Unix mail systems that can completely replace the Sendmail-Binmail system. Qmail has a lot of features compared to Sendmail, including:
Safety ---- qmail divides the MAIL process into multiple processes, trying to avoid ROOT users
Run. At the same time, QMAIL prohibits direct delivery of privileged users (root, deamon, etc.)
letter.
Reliable ---- QMAIL direct delivery guarantee that email will not be lost during delivery.
Qmail supports new and more reliable mailbox format maildir, ensuring the system
The entire mailbox is not destroyed under sudden crash.
Efficient ---- On the BSD / OS running in the Pentium, QMail can be easily delivered every day 200000
Sealing letter.
Simple ---- qmail is much smaller than other Internet mail systems. Qmail through
One forward mechanism completes Forwarding, Alias and Mailist etiquette
Yes, qmail uses a simple and efficient queue to handle delivery. Qmail-smtpd can be
Inetd starts and saves a certain resource.
QMAIL support: host and user masquerading
Full host Hiding
Virtual Domains
Null Clients
List-owner shutriting
Relay Control
Double-Bounce Recording
Arbitrary RFC 822 Address Lists
Cross-host mailing list loop detection

Modify all the files under the vqsignup_text directory so that they only contain you
If you want to support the domain, you can customize these pages to make them more well.
Modify the vqsignup.html file in the documentroot directory, make it only
Contains the domain you want to support, you can customize this page so that it is better
Look at it.
d. test
Use your browser to access http: // your web server / your sub Dir / vqsignup.htm, try to register new users, if successful,
So congratulations. If there is an error, return to the installation step to carefully view the permissions of the file and whether the value in vqsignup.html is correct. & 2.4 Other Resources

QMAIL configuration work is greatly simplified than Sendmail, but wants to truly establish a powerful, running a mail server, mastering its flexible configuration, carefully reading its how-to and faq is necessary. About Dot-Forward, Mail List, etc. A very useful method and use skills are limited to the space, it is recommended to refer to the relevant documentation in the package.
