Build Iredmail mail server under Linux

Iredmail is an open-source, free mail server project that is published under the GPL (V2) protocol. Official website www.iredmail.org (domestic not accessible), can be accessed through www.iredmail.com.

Iredmail is a good Post Office Server free solution for small businesses, individuals or teams to build internal staff mailbox services;

Using Iredmail to build a mail server requires a public network of CentOS hosts. Recommended use of VPS;

Iredmail core components and their corresponding functions:

POSTFIX:SMTP Server

Dovecot:pop3/imap/managesieve Server

Apache:web Server

MySQL: Data that is used to store other programs, and can also be used to store mail accounts.

OpenLDAP: Used to store mail accounts.

Policyd:postfix Policy Server

AMAVISD: Provide DKIM signature and checksum, SPF Check, add "disclaimer" content for outgoing mail, and call SpamAssassin to do spam scanning based on message content, call ClamAV to do mail virus scan.

Roundcube: Web mail;

Awstats: Used to parse Apache and Postfix log files and generate simple charts.

Fail2ban: Scan various log files, found multiple password errors and other conditions can automatically block the other IP for a period of time. Used to ensure server security.

Iredadmin: Web-based mail account management program.

1, Iredmail Installation

Pre-preparation work, need to apply for an independent domain name, you can go to million or new network to buy domain names;

and purchase VPS, install the CentOS system, have a separate IP address; This simulation uses the huangxiaofan.com domain name;

The steps are as follows:

Hostname mail.huangxiaofan.com

Vim/etc/hosts//Join

127.0.0.1 mail.huangxiaofan.com

Configure DNS resolution in the Background settings for domain purchase:

MX record mail.huangxiaofan.com

A record put mail.huangxiaofan.com point to a VPS IP, this IP is we want to do mail server IP

wget http://www.iredmail.com/iRedMail-0.9.1.tar.bz2

(Currently the latest version is 0.9.1, will change later, please go to http://www.iredmail.com/download.html to download the latest version)

If your server is a domestic server, you need to do some processing before you install it:

Tar jxvf iredmail-0.9.1.tar.bz2

CD iredmail-0.9.1/pkgs

VI get_all.sh//change https://mirrors.fedoraproject.org to Http://mirrors.fedoraproject.org

Sed-i ' s/iredmail.org/106.187.51.47/g ' get_all.sh

Cd..

The U.S. VPS does not need to do the above operation, direct sh execution script;

SH iredmail.sh

After execution, we need to download the installation package, and then go to the graphical installation interface after completion.

Send large attachment content 2M, upload attachment speed is very slow, QQ mailbox charge about 1-2 minutes, QQ sent over the reception is very slow, more than 10 minutes;

e-mail is normal, the mail is very slow, because the Policyd service caused by the solution:

vim/etc/policyd/cluebringer.conf//Find greylisting This module, in front add #

Then restart the Dovecot/postfix/cbpolicyd service:

Service Dovecot Restart; service Postfix restart; Service Cbpolicyd Restart

Simple mail server set up, for small and medium-sized enterprises need to consider the use;
