SPF, which is short for Sender Policy Framework, is an email security system, which is is intended to validate whether an email message was sent by a certified server. Employing SPF protection for a particular domain will prevent the forging of email addresses created with the domain. In layman's terms: enabling this attribute for a domain creates a special record in the Domain Name System (DNS) containing the IP addresses of the servers which are permitted to send e-mails from mail boxes using the domain. The moment this record propagates globally, it will exist on all the DNS servers that route the Internet traffic. Any time some e-mail message is sent, the first DNS server it uses tests if it comes from an approved server. If it does, it is sent to the destination address, but if it doesn't originate from a server listed in the SPF record for the particular domain, it is rejected. Thus nobody can mask an email address and make it look as if you are e-mailing spam messages. This method is also known as email spoofing.
SPF Protection in Hosting
You'll be able to enable the SPF protection option for your domains with a couple of clicks in the Hepsia Control Panel, which is provided with all of our Linux hosting. This carried out from the section bearing the very same name and you are able to enable the protection for each domain part of our innovative cloud platform. Using a really time and effort saving interface, all you have to submit is the hostname of the mail server that will be authorized to send out messages from your emails and its IPv4 or IPv6 address. Of course, you are able to include several servers too, if needed. In case your email addresses are handled by us, you can also take advantage of a more secure option by putting a restriction that email messages can be sent only if your domain names have our MX records. This solution cannot be used in case your site is hosted here, but your emails are with a third-party service provider. In either case, the SPF protection solution can really improve your web security and stop others from forging your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
The Hepsia web hosting Control Panel, which comes as standard with all our Linux semi-dedicated hosting, will provide you with a really easy-to-use interface to activate the SPF security service for any domain that you host within your new account. Several clicks in the Emails section of Hepsia are enough for that and you'll only have to enter the hostname and the IP address of the mail server that will be allowed to send out messages from your emails. When the e-mails are taken care of by us and not by some other supplier, you can raise the protection level even further and enable an option for all of the outgoing e-mails to be sent only if your domains feature our MX records. This option will give you better control and it'll eliminate any possibility of someone faking your email addresses with the purpose of spamming or scamming people. It's not applicable when just your website is on our hi-tech cloud hosting platform, while your e-mails are managed by another service provider. If you are not sure what options to choose, our technical support crew will assist you 24/7.
