The guide how to work with the iRedMail (IMAP, SMTP, POP3) Email Server on Ubuntu 18.04 LTS on amazon

Minimal VM (virtual machine) configuration – B1ms

core 1



Recommended VM configuration

core 2

GB RAM 4-8


1. Static Ip address  – Your virtual machine should have the static IP address, if you want constantly change the domain settings (because if the address is dynamic, after the rebooting of the machine it’ll change to the static one).

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

The instruction how to do that:

Google Domain –

Namecheap –

GoDaddy –

iRedmail mx setup information

(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)


The 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/

* You can login to above links with below credential:

– Username:

– Password: postmasterpwd

* – Web admin panel (iRedAdmin): https://youVirtualMachineIP/iredadmin/



Change the default password on this page ( Admins -> All Admins -> Edit accont)


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

Type the new password and save the changes 


Add domain name in admin panel.

Login to mailbox (test account)

* – Roundcube webmail: https://youVirtualMachineIP/mail/  (http://youdomain/mail)

Here you should enter the data that was changed before
In our case these are:

– Username:

– Password: newpassword (or if you haven’t changed your password – then enter postmasterpwd )

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

The default password: postmasterpwd (if you haven’t changed your password)

The access to the mailbox through the mail client
