Guide – How To Start – iRedMail on CentOS Stream 9 on Amazon

Configuring and connecting to iRedMail on CentOS Stream 9

Start your VM

It is recommended to use the Instance type “t2.medium” or higher when installing the VM. To start the server, you just need to start the VM.

To customize the Server, first, you need to know the server IP address. You need to select the virtual machine from the list. Your IP is displayed in the line “Public IPv4 address”.

For the server to be usable, open TCP ports 25, 80, 110, 143, 443, 587, 993, 995 in your VM’s security group.

Static IP address – Your virtual machine should have the static IP address if you do not want to constantly change the domain settings (because if the address is elastic, after the rebooting of the machine it’ll change to the static one).

Get a random admin password

To get the password, you should connect to the VM. To do that, generate a “Private Key” in advance. This can be done using the following instructions (by choosing the “file format:” option “.ppk” in point 3) Guide – How To – Create and use Key Pair to connect to a VM

Download and run Putty

Go to the “SSH” section in the left panel (1) and then to “Auth” (2).

In the “Auth” section, click “Browse” and specify the path to the .ppk file you received earlier.

Go to the home page of “Session”, enter the IP address of the VM (1), and click “Open” (2).

In the opened console, you will need to enter the login ec2-user

Connect to your server

After creating the machine, it’s possible to get access to the web panel either directly through the IP address or by adding to the domain MX records

The instructions on how to do that:

Google Domain – https://support.google.com/a/answer/6248174?hl=en

Namecheap – https://protonmail.com/support/knowledge-base/dns-records-namecheap/

GoDaddy – https://www.godaddy.com/help/what-is-an-mx-record-324

iRedmail MX setup information https://docs.iredmail.org/setup.dns.html#mx

For your site, where you’ve bought the domain – please, google “youdomainSeller add MX records” or contact seller customer support.

Please, consider that it’s better to use the static IP address for the mail server. Sometimes it takes up to 24 hours to activate the MX records.

Access to the inbox – through the web-panel

Here is the default data for the connection. As an example, we have taken the IP address of our VM. Instead of it, you should write yours
– Web admin panel (iRedAdmin): https://youVirtualMachineIP/iredadmin/ (http://youdomain/iredadmin/)

– Roundcube webmail: https://youVirtualMachineIP/mail/

(http://youdomain/mail/)

Login to admin panel – https://youVirtualMachineIP/iredadmin/

You should enter the following credentials:

– Username: postmaster@example.com

– Password: postmasterpwd

The next window opens

To change the default password on this page, go to Admins -> Edit account

After you have opened the window of settings, go to the Password tab

Enter (1) and reenter (2) the new password and save (3) the changes

To add a domain name in the admin panel go to Domains and Accounts -> Add domain

Login to the mailbox (test account) – https://youVirtualMachineIP/mail/

You should enter the following credentials:

– Username: postmaster@example.com

– Password: postmasterpwd

The next window is displayed

The password change for the mailbox (not for the admin’s account):
Settings > Password > Type the current password > Type the new password > Save
