I want to create my own mail ID like instead of paying extra to google for extra mail ids as I have already

Things I have are paid for this domain name and this is pointing to our staging server say IP xx.xx.xx.xx), system with Ubuntu server.

I tried setup Postfix, when install Postfix server

Internet site:
Root and postmaster mail recipient: root
mydestinations:,, localhost

rest all default.

Now I am able to send mail from postfix mail server by command $ sendmail 'message'. I checked I got mail from I try reply to from but there is no mail received under root. This is the file in ubuntu server /var/mail/root where mails received, it is empty.

I want if someone send mail to should be saved in ubuntu server.

Please let me know if you don't understand my question.


There is no MX in I did dig mx where should I set MX whether in staging server or in where we bought this name from.

Result of dig mx is ;;QUESTION SECTION: IN MX ;;AUTHORITY SECTION: 7200 IN SOA 201...3 7200 7200.

Result of telnet 25 gives Trying I guess port 25 in staging server is blocked by firewall. I need to contact my admin to allow port 25.

Many ISPs block port 25, so you can use port 587 as an alternative, or secure SMTP on port 465 – user268693 Dec 3 '13 at 11:44

If it hasn't an MX, then it should have an A. If haven'tany of them, how could gmail find out the ip address of the receiver mailserver?
