This article mainly introduces the steps of building a mail server in Redhat Linux. In daily operation, I believe many people have doubts about the steps of building a mail server in Redhat Linux. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about how to build a mail server in Redhat Linux. Next, please follow the editor to study!

First, configure the experimental environment.

Bind provides DNS service parsing

Domain name: liusuping.com

Service acts as both a DNS server and a mail server

Server domain name: mail.liusuping.com IP:192.168.0.231

Set the mx record of the mail server

Apache provides web service, which is a necessary option for openwebmail.

Sendmail and dovecot are available in the installation shutdown. Openwebmail and related components need to be downloaded from the website: http://www.openwebmail.org/openwebmail/download/

Install sendmail

[root@mail] # rpm-ivh / media/Server/sendmail-8.13.8-2.el5.i386.rpm

[root@mail] # rpm-ivh / media/Server/sendmail-cf-8.13.8-2.el5.i386.rpm

[root@mail] # rpm-ivh / media/Server/m4-1.4.5-3.el5.1.i386.rpm

Modify / etc/mail/sendmail.mc

Configure mail server address and domain name

DAEMON_OPTIONS (`Port=smtp,Addr=0.0.0.0, Name=MTA') dnl

LOCAL_DOMAIN (`liusuping.com') dnl

To add smtp authentication, you need:

TRUST_AUTH_MECH (`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN') dnl

Define (`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN') dnl

DAEMON_OPTIONS (`Port=submission, Name=MSA, MageEa') dnl

Generate the sendmail.cf master configuration file

[root@mail ~] # cd / etc/mail

[root@mail mail] # M4 sendmail.mc > sendmail.cf

Install dovecot

Let mail support using MUA to receive mail

First of all, you need some package support:

[root@mail mail] # rpm-ivh / media/Server/postgresql-libs-8.1.4-1.1.i386.rpm

[root@mail mail] # rpm-ivh / media/Server/perl-DBI-1.52-1.fc6.i386.rpm

[root@mail mail] # rpm-ivh / media/Server/mysql-5.0.22-2.1.i386.rpm

Install dovecot

[root@mail mail] # rpm-ivh / media/Server/dovecot-1.0-1.2.rc15.el5.i386.rpm

Modify / etc/dovecot.conf

Remove comments

Protocols = imap imaps pop3 pop3s

Listen = [:]

Start the sendmail and dovecot services

Service sendmail start

Service dovecot start

Mail aliases, group

/ etc/aliases join

Liusuping: frank,frankliu

Let the newly added group take effect

[root@mail mail] # newaliases

/ etc/aliases: 77 aliases, longest 14 bytes, 788 bytes total

Forwarding control

[root@mail mail] # vim / etc/mail/access

Add one line, 192.168.0.0 is the network segment where the server resides

Connect:192.168.0.0 RELAY

Regenerate access data

[root@mail mail] # makemap hash access.db < access

Install openwebmail

Required package:

[root@mail tmp] # rpm-ivh / media/Server/perl-suidperl-5.8.8-10.i386.rpm

[root@mail tmp] # rpm-ivh perl-Text-Iconv-1.7-1.el5.rf.i386.rpm

[root@mail tmp] # rpm-ivh openwebmail-data-2.53-3.i386.rpm-nodeps

[root@mail tmp] # rpm-ivh openwebmail-2.53-3.i386.rpm

Check dbm.conf configuration

[root@mail tmp] # vim / var/www/cgi-bin/openwebmail/etc/dbm.conf

Dbm_ext .db

Dbmopen_ext .db

Dbmopen_haslock no

Initialize the openwebmail configuration:

[root@mail tmp] # / var/www/cgi-bin/openwebmail/openwebmail-tool.pl-- init

Welcome to the OpenWebMail!

This program is going to send a short message back to the developer

So we could have the idea that who is installing and how many sites are

Using this software, the content to be sent is:

OS: Linux 2.6.18-8.el5 i686

Perl: 5.008008

WebMail: OpenWebMail 2.53 20080123

Send the site report? (YBO) n

Thank you.

Modify openwebmail.conf file, Chinese culture

[root@mail tmp] # vim / var/www/cgi-bin/openwebmail/etc/openwebmail.conf

Default_language zh_CN.GB2312

Default_iconset Cool3D.Chinese.Simplified

Start the http service.

Visit http://mail.test.com/cgi-bin/openwebmail/openwebmail.pl

Since the access domain name is too long, you can add redirect and add index.html in / var/www/html/, which is as follows:

Complete the configuration, visit http://mail.liusuping.com, test webmail, and then send and receive email through client test pop3 and smtp.
