It is dynamic ip address. I think, it is the router's public ip address. Local pc has ip address like 192.168.1.103.
I am trying to send email to gmail through postfix with port 25 from local pc or localhost. I have installed postfix, opendkim and configured these. /etc/hostname has "mydomain.com". So the sender is user1@mydomain.com.
