Creating DKIM TXT Records in Linux/UNIX BIND

https://www.unifiedemail.net/Support/KB/DomainKeys-Identified-Mail-(DKIM)-Setup-Linux-UNIX-BIND/

Add a new "Text (TXT)" resource record, enter the following:

Record name: (DKIM Selector)._domainkey.yourdomain.com.

Example: ue201009._domainkey.yourdomain.com.

Text: (This should be the value of your DKIM Public Key Record).

Record name

The record name should be ._domainkey prefixed with the selector name:

default._domainkey.

Any sub domain information should be appended, which opendkim-genkey doesn't do. for sub.domain.example.com you should use:

default._domainkey.sub.domain

TXT value

The value should include a minimum of the DKIM version, key and key type:

v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDbpMiQR1EMmOmCYzzuHYlXho97NnX1/nFCftJLjY2NVkGlCdxMpnnoVI3oGeM1DmzdbC9eySW+GbFnPs0FrPB5Tqod1XXYI3gwrMihIyMJfsIMAU0EPJKvJjwsELNYj4UHWBhWIjusGw0AeDQuUH0sCYOkdPkOSvM2wpZsvHkDZwIDAQAB

How to install and integrate DKIM with OpenDKIM and Postfix on a CentOS 6 VPS

https://www.rosehosting.com/blog/how-to-install-and-integrate-opendkim-with-postfix-on-a-centos-6-vps/

assuming the domain in question is ‘mydomain.com’ and server’s hostname is set to ‘host.mydomain.com’

finally, edit your mydomain.com DNS zone and add the TXT record from /etc/opendkim/keys/mydomain.com/default.txt

default._domainkey      IN      TXT     ( "v=DKIM1; k=rsa; "

          "p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDApHRr7ZmXRaAB+RQRbP4VdMwIrIHIP18KFtXRsv/xpWc0Gix6ZXN13fcG03KNGKZo2PY+csPkGC5quDnH5V0JEhDZ78KcDWFsU6u4fr9ktVAdt6P7jWXjcyqdHOZ8+YN4cAeU4lRFNgQvdupIcByYwzPYMgBFHfJm9014HvRqhwIDAQAB" )  ; ----- DKIM key default for mydomain.com

음.. 무슨 짓을 해도 안된다..

공백은 \로 표현하는듯.. 

음..그리고 파일 수정 후 service named restart 해보면 새로 시작되는데 

(새로시작하지 않아도 적용되긴하는듯)

잘못설정하면 새로 시작할 수 없다고 에러가 난다.

근데 왜 에러가 없는데도 공개키를 읽지 못하는 거지.
