I want to create my own mail ID like myname@mydomain.in instead of paying extra to google for extra mail ids as I have already myname@mycompany.in.

Things I have are mydomain.in(I paid for this domain name and this domain.in 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:  mydomain.in.
Root and postmaster mail recipient: root
mydestinations:  mydomain.in, localhost.example.com, localhost

rest all default.

Now I am able to send mail from postfix mail server by command $ sendmail myname@gmail.com 'message'. I checked myname@gmail.com I got mail from root@mydomain.in. I try reply to root@mydomain.in from myname@gmail.com 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 root@mydomain.in should be saved in ubuntu server.

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


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

Result of dig mx mydomain.in is ;;QUESTION SECTION: mydomain.in IN MX ;;AUTHORITY SECTION: mydomain.in 7200 IN SOA dns1.bigrock.in. 201...3 7200 7200.

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


I get failure notice to my gmail account back

Delivery to the following recipient failed permanently:


Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain mydomain.in by us2.mx2.mailhostbox.com. [].

The error that the other server returned was:
550-5.1.1 <fmaster@mydomain.in>: Recipient address rejected: User unknown in virtual alias table
550 5.1.1 Please see http://support.mailhostbox.com/email-administrators-guide/error-codes for explanation of the problem.
  • 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?
