I am using postfix to set up mail. Currently, the following tasks have been completed.
·Install postfix
·Setting main.cf, master.cf
·Send test with mail command
·Build GUI operation by webmin installation
Currently, we are able to confirm the sending of the mail to the account we created on the server. Currently, however,
I have sent it to , but I have sent it here
I would like to send it to .
For now, when I send an email to [email protected], the ISP sends me an error Unknown message.
There is no description of the network configuration, so I can only write generalizations, but if it is in the category of this question, it may be necessary to set the DNS MX record for the retrieved domain before setting Postfix.
ASCII.jp: Domain name and DNS mechanisms to support mail (1/2)|E-mail Secrets
A normal mail address includes a "domain name" indicating an organization to which a destination user (mail box) belongs.However, this domain name is given to a group such as an organization, not a specific server.For example, in the case of a Web server, a communication partner is identified in the form of a host name, such as tech.ascii.jp.In the same way, the host name of the mail server which is originally the destination of the mail should be designated.Of course, some ISPs add the name of the mail server (information shown in ) to their e-mail addresses, such as "@m ta.biglobe.ne.jp".However, many companies use domain names only, such as @a-scii.co.jp.So how do you identify the mail server from the domain name?In conclusion, this is due to Domain Name System (DNS).
