Using the VPS mail service with Plesk

On our VPS's you can always use our mail service free of charge, also referred to as 'Carefree Mailing'. With this service you will use our mail services to relay outgoing e-mail. In order to use the mail service, a one-time configuration of Postfix on your VPS is required.

When using the mail service you will no longer have to worry about mails being delivered in the spamfolder due to incorrect reverse DNS or SPF-records, or because a blacklist is blocking mails from your IP-address.

To successfully set this up you will need to perform some configuration changes on your VPS to make sure your VPS and domains are properly authenticated for the use of our platform.

The easiest method for configuring the mail service is using the wizard in the control panel. Click here to immediately be taken to the wizard.

Configuring Postfix manually

Use these steps if you're not using the wizard. First, consult this article if you haven't already, in order to retrieve your username and password, as well as to configure the required DNS records for your domain. Then, follow the steps below in your VPS-console or using SSH.


Step 1

Log in onto the console or via SSH and make sure you are running as 'root' or follow all the steps via the 'sudo' command.


Step 2

Open the file /etc/postfix/ :

nano /etc/postfix/


Step 3

Scroll down to the bottom of the file and add the following:

relayhost =
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_use_tls = yes
smtp_tls_security_level = encrypt
smtp_tls_note_starttls_offer = yes

Please note! The default Postfix-config will have some of these settings by default commented out via a #. If they are not, please check these and edit if necessary to prevent conflicting settings. All referrals to 'smtpd_' can be left alone.


Step 4

Create and open /etc/postfix/sasl_passwd file:

nano /etc/postfix/sasl_passwd


Step 5

Add the content below to the file:

Replace the username and password with your own mail service credentials.


Step 6

Save the changes and close the file by pressing ctrl + x > y > enter.


Step 7

Execute the command:

postmap hash:/etc/postfix/sasl_passwd

If you get an error, it's possible you will first need to install the 'cyrus-sasl-plain package':

yum -y install cyrus-sasl-plain


Step 8

Reload Postfix to process the changes:

systemctl restart postfix

You are now ready to start using the VPS mail service!
