You may know Icewarp mail server. it’s one of the leading mail server software that offers a lot of great capabilities and features. in this article we want to describe how to install Icewarp mail server on CentOS 7 Linux.

if you want to know more about Icewarp mail server, please refere to Icewarp web site. also you can download latest linux version of Icewarp from here.

Here are our environment OS and software versions:

OS: Centos 7.6 on VMware
Database: Mariadb 10.3
Number of Disks: four 500 GB
Disk Layout: LVM
Firewall: CSF

1- Initial Setup

In Icewarp you can choose whether to use database engine or sql lite for storing informations.

here we use database engine with replication for better high availability. if you wanted to know how to setup replication you can refer to database replication with mariadb on CentOS 7 linux.

Also for storing user emails, we use four 500 GB disks with lvm layout. to know about lvm setup, refer to how to create LVM with four disks on CentOS 7 linux.

In addition, refere to how to install CSF on CentOS 7 Linux and put the following configuration in csf.conf:

# TCP_IN = "21,22,25,80,110,143,443,465,587,636,990,993,995,1080,2703,3306,4567,4568,4444,4069,4070,4567,5160,5222,5223,5229,5269,7830,8822,8899,32000,32001"
# TCP_OUT = "21,22,25,80,110,143,443,465,587,636,990,993,995,1080,2703,4069,4070,4567,5160,5222,5223,5229,5269,7830,8822,8899,32000,32001"
# UDP_IN = "20,21,53,10000:10250,32002"
# UDP_OUT = "20,21,53,10000:10250,32002,4567"

2- Create required databases

In previous step we decided to use database engine for storing icewarp data. Icewarp has some databases that needs to be created.

so login to mariadb and tun the following commands:

# mysqladmin -u root -p create icewarp_accounts collate='utf8_general_ci';
# mysqladmin -u root -p create icewarp_antispam collate='utf8_general_ci';
# mysqladmin -u root -p create icewarp_groupware collate='utf8_general_ci';
# mysqladmin -u root -p create icewarp_dircache collate='utf8_general_ci';
# mysqladmin -u root -p create icewarp_webcache collate='utf8_general_ci';
# mysqladmin -u root -p create icewarp_webmail collate='utf8_general_ci';
# mysqladmin -u root -p create icewarp_activesync collate='utf8_general_ci';
# mysqladmin -u root -p create icewarp_reports collate='utf8_general_ci';
# mysqladmin -u root -p create icewarp_loganalyzer collate='utf8_general_ci';

verify created database by logging in to mysql on DB servers

# mysql -u root -p
# SHOW databases;

grant privilege to icewarp server on database

# mysql -u root -p

Enter password:

# mysql>GRANT ALL ON *.* to root@'192.168.1.1' IDENTIFIED BY 'put-your-password';
# mysql>FLUSH PRIVILEGES;
# mysql>exit
