After complete setup Cyber Panel

Hi,
After complete setup Cyber Panel and added emails accounts as per 01 - Installing CyberPanel - Docs - CyberPanel Community and Create Email Server/Accounts on Cyber Panel & the inbuilt Email Marketing Feature - YouTube

Email is not sending thru rainloop, Error Cann`t send meesage.

I was trying to send first mail to mail-testerdotcom

Please guide me how can we send receive email thru server SMTP

Perhaps your port 25 is blocked or postfix/dovecot service is not running. Check with following commands.

telnet smtp.gmail.com 25
output should be connected status
systemctl status postfix
status should be running. If not start postfix
systemctl start postfix

Thanks. All were okay. issue was with dns. Now fix the problem .
