Sender Policy Framework, or SPF, is a validation system, which is used to prevent the so-called e-mail spoofing where an email message is sent from one address, but to look as being sent from a different one, generally with the idea to scam the recipient someway. If SPF protection is activated for a domain name, a special record is generated for it in the Domain Name System and all of the DNS servers around the world get it. The record contains all of the email servers that are allowed to send authentic messages from an address part of the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and when its sending server is permitted, the message is forwarded to the target receiver. When, however, the sending server doesn't exist in the SPF record for the specified domain, the email message will not be sent and it will be discarded. When you use this service, it'll prevent third parties from sending spam emails that look as if they have been sent by you.
SPF Protection in Cloud Website Hosting
SPF protection can be activated for any domain hosted in a cloud website hosting account on our cloud hosting platform with just a couple of mouse-clicks. The function can be found in the Emails section of our state-of-the-art Hepsia Control Panel and what is needed to activate it is to select one of your domains from the drop-down list and type in the hostnames and the IPv4 or IPv6 addresses of the mail servers that will be permitted to send messages from your email addresses. As an additional option you can even restrict the emails to be sent from your domain name only if it includes our MX records, i.e. if our servers manage the email addresses for it, not some third-party supplier. This solution will give you the best degree of protection, but it is not applicable in case only your web site is on our servers while your email addresses for the domain are managed elsewhere. Regardless, our SPF protection service will keep your emails secure from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from our company, you will be able to protect your email addresses by activating the SPF security service for every domain in your account with just a couple of clicks. This can be done through the Emails section of the Hepsia Control Panel which comes with the semi-dedicated accounts and even in case you have no previous practical experience with these kinds of matters, you will not have any trouble to activate the protection. Everything that you'll have to do will be to choose a domain name from a drop-down list then type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your emails will be sent around the world only if they were sent from that specific server. If your email addresses are handled by our company and not by a third-party supplier, you'll also be able to use an option for e-mail messages to be sent only when the domain includes our MX records and this would be the safest option. Should you have any kind of questions related to thisfeature, you'll be able to contact our support team 24/7.
