I guess you sent outgoing mails to the wrong (external) port. You need to use the internal port instead.
 
hi
Thanks for you replying i am using outing port is 25 on outlook configuration as well proxmox .

proxmox : mail proxy is SMTP Port is 25 check given pic . and also add this port on my actually email server.

my internal server i add this line : i am using postfix
relayhost = proxmox.cubexs.net.pk:25

First, please fix the CIDR "38.108.7.55/24". Second, seems you still send to port 25 - you need to inject outgoing mails on port 26,

Code:
relayhost = proxmox.cubexs.net.pk:26
