The SPF and DKIM records are a type of Domain Name Service records.
This post helps you to enable DKIM and SPF for all accounts in cPanel
with a script. The purpose of these records is to prevent spammers.
The
SPF (Sender Policy Framework) identifies which
mail servers are permitted to send email on behalf of your domain.So it
will prevent spammers from sending messages with forged “From addresses”
at your domain.
DKIM (DomainKeys Identified Mail) is an email
validation system designed to detect email spoofing by providing a
mechanism to allow receiving mail exchangers to check that incoming mail
from a domain is authorized by that domain’s administrators and that
the email (including attachments) has not been modified during
transport.
We can simply enable the SPF and DKIM records from cPanel (
Home >> Mail >> Email Authentication).
If you need to enable DKIM and SPF for all accounts in cPanel, it is
not possible to manually enable them via cPanel. In that case you can
use the following script.
To Enable:
cat /etc/trueuserdomains | cut -d: -f2 >> /root/users.txt
for i in `cat /root/users.txt` ;do /usr/local/cpanel/bin/dkim_keys_install $i ;done
for i in `cat /root/users.txt` ;do /usr/local/cpanel/bin/spf_installer $i ;done
To Disable:
Also, you can disable the DKIM and SPF records on all accounts in cPanel using the following script.
cat /etc/trueuserdomains | cut -d: -f2 >> /root/users.txt
for i in `cat /root/users.txt` ;do /usr/local/cpanel/bin/dkim_keys_uninstall $i ;done
for i in `cat /root/users.txt` ;do /usr/local/cpanel/bin/spf_uninstaller $i ;done
That’s it!
