Hi @Abbirami
After upgrading RHEL8, it is possible that some services or configurations related to email might have been affected. To troubleshoot the issue and determine if a restart is necessary, you can follow these steps:
1. Check the email service status: Verify if the email service is running by checking the status of the relevant service. On RHEL8, the most common email service is postfix. You can check its status by running the following command:
systemctl status postfix
If the service is not running, you can start it using the following command:
systemctl start postfix
2. Check the email logs: Examine the email logs to identify any errors or issues. The logs are typically located in the `/var/log/maillog` file. You can view the last few lines of the log file using the following command:
tail -n 50 /var/log/maillog
Look for any error messages or indications of failed email deliveries. This can help identify the root cause of the problem.
3. Verify email configuration: Ensure that the email configuration is correct. Check the configuration files for the email service (e.g., `/etc/postfix/main.cf`) and verify that the necessary settings, such as the mail server address and authentication credentials, are correctly configured.
4. Test email delivery: Send a test email to verify if the email service is functioning properly. You can use the `mail` command to send a test email. For example:
echo "This is a test email" | mail -s "Test Email" your-email@example.com
Check if you receive the test email in your inbox. If not, there may be an issue with the email service or the email server configuration.
If the above steps do not resolve the issue, it may be necessary to restart the email service or other related services. You can restart the email service using the following command:
systemctl restart postfix
Additionally, if there were any other system services or components that were upgraded or restarted during the RHEL8 upgrade, it may be worth considering restarting those services as well.

Hi,
It may be related to SELinux. Please check its status and add the proper configuration if it has been overwritten. You can find more details here: https://tecadmin.net/how-to-disable-selinux-on-centos-8/
Hope this helps
