Enable SPF and DKIM Key in CWP

In this tutorial we will be guiding you on how to enable SPF and DKIM in CentOS Web Panel.

 

1) Login to CWP (http://your-ip.com:2030)

 

2) Navigate to Email --> Postfix Manager and tick mark Install DKIM & SPF: and click on Rebuild Mail Server

 

3) Now goto Email --> DKIM and SPF Manage and Select Domain Name, tick enable spf and then click Add DKIM

 

As you see in above image v=spf1 is not enabled yet. Lets enable SPF manually.

 

4) Navigate to DNS Function --> List DNS Zones and there you will see your domain name and infront of it there is Edit File button. Click Edit File and Add below entry.


your-domain-name. 14400 IN TXT "v=spf1 +a +mx +your-ip-address ~all"

 

You have successfully enabled SPF. Now lets make DKIM verification working.

 

5) open /etc/opendkim/TrustedHosts and add your hostname.

nano /etc/opendkim/TrustedHosts

 

6) open /etc/postfix/main.cf and add the lines below.

nano /etc/postfix/main.cf

smtpd_milters = inet:127.0.0.1:8891
non_smtpd_milters = $smtpd_milters
milter_default_action = accept
milter_protocol = 2

 

7) Finally restart postfix.

 

service postfix restart

 

You are done with enabling SPF and DKIM Keys. Now login to webmail (http://yourdomain.com/webmail) and send email to [email protected] to verify if everything is setup correctly.

 

*Note: In version 0.91+ you dont need to proceed with point 6 and 7
