How to Install Domain Key on cPanel server
You can install domain keys on a cPanel server easily for a single domain, in this tutorial I am using cPanel 11.
Run the following command shown below:
[root@afrizal etc]# /usr/local/cpanel/bin/domain_keys_installer username
(i.e.: /usr/local/cpanel/bin/domain_keys_installer afrizal)
It will automatically installing Domain Key for the domain (zall.us) successfully.
Now you can verify it from the db record of the domain. The following new entry will be added in the db record.
[root@afrizal etc] vi /var/named/zall.us.db
; cPanel 11.23.3-CURRENT_25049
; Zone file for zall.us
$TTL 14400
@ 86400 IN SOA ns1.e-padi.com. zall.e-padi.com. (
2008111500 ; serial, todays date+todays
86400 ; refresh, seconds
7200 ; retry, seconds
3600000 ; expire, seconds
86400 ) ; minimum, seconds
zall.us. 86400 IN NS ns1.e-padi.com.
zall.us. 86400 IN NS ns2.e-padi.com.
zall.us. IN A 75.125.178.242
localhost.zall.us. IN A 127.0.0.1
zall.us. IN MX 0 mail.zall.us.
mail IN CNAME zall.us.
www IN CNAME zall.us.
ftp IN A 75.125.178.242
default._domainkey IN TXT “k=rsa; p=MHwwDQYJKoZIhvcNAQEBBQADawAwaAJhAMZmC4FHl63UcC9o1Q3V72dp8DLjp;”
Now run command below:
[root@afrizal etc] rndc reload zall.us
[root@afrizal etc] /etc/rc.d/init.d/exim restart
Now you can verify it by creating a new mail account iam@zall.us and send an email to yahoo account, then verify the headers.
