Email service not working from Proxmox VMs and Containers

We have installed application In Proxmox VM to our alert system and configured Gmail to send alerts But we are not getting email alerts
I tried with both VMs and Container but no luck whereas the system outside Proxmox can deliver emails form the same application.
The apparition we are using is Zabbix, in that SMTP server port we are using is 25
Please let us know if we need to enable something in Proxmox base system or somewhere

I have noted something in the base system
The email configured in Datacenter -> user -> root (pam) -> email is also not delivering emails
whereas the I am getting email alerts for a daily backup
have you installed and configured an MTA (postfix) on the PVE-node?
check the journal for hints to what is not working properly

I hope this helps!
