I have a brand new Web Server (www.tunefind.org
), and it is collocated to an ISP (Internet Service Provider) near my office. The IPS suggested me to use Postfix rather than Sendmail for Mail Transport Agency. Right now, I have a temporarily setup that the ISP's other host machine play the role of MTA (Mail Transport Agent) as the name of "mail.tunefind.org". It was fine for a little while, but I have a desire to send and receive emails directly from the own Web Server machine (18.104.22.168 - www.tunefind.org
Then, I started my challenge to configure Postfix Mail server. I learned that,
is the configuration file about most control over Postfix. Then I learned that,
makes activate Postfix deamon. Now, at least on that Server machine, Postfix deamon is running. As shown below.
The first problem is there is a competetion between Sendmail and Postfix in the machine, and I don't know how to fix only to the Postfix as MTA.
The second problem is that I don't know how to test email-sending and receiving while another machine is currently assigned the role of "mail.tunefind.org". At least I want to send email out from (22.214.171.124 - www.tunefind.org
), but I do not know any way to test it.
I think I have to go through many challenges, but please advice me piece by piece of knowledge I have to learn and know, to fulfill my goal. Thank you ! I attach my DNS report status, so that you, experts, may suggest the health of my domain's setting.
Here is a little bit of /var/log/maillog,
