Postfix sending and receiving in strange way.

I have an email server, running on CentOS 6.5, 32bit system, with Postfix and Dovecot running along all their dependencies. Let's assume my domain is www.anw.com

I have created A record in this order for my domain

    www.anw.com         37.143.374.15    # points to my web server
    anw.com             37.143.374.15    # points to my web server
    mail.anw.com        227.80.74.199    # points to my mail server

I have also created an MX server

   mail.anw.com    227.80.74.199

Now, using postfix I have created two accounts, namely [email protected] and [email protected] using squirrelmail I can send and receive between those accounts without any problem. I can also send emails to any email account like Yahoo and Google, but I can't receive emails sent from Google or Yahoo.

In your /etc/postfix/main.cf look at the following settings and the associated comments:

myhostname (your mail server's host name) mydomain = dailytech24.com (you domain name) myorigin = $mydomain inet_interfaces = all (if you only have IPv4 then this needs to change) mydestination mynetworks

Your Postfix is listening only on the Loopback interface (127.0.0.1). Edit the /etc/postfx/main.cf file and update the inet_interfaces parameters with your public IP address.

inet_interfaces = MY.IP.AD.DR,127.0.0.1

You will then have to restart the Postfix service.

# service postfix restart
