SPF, which is short for Sender Policy Framework, is an e-mail protection system, which is is intended to confirm if an e-mail message is sent by an official server. Using SPF protection for a given domain will prevent the forging of email addresses made with the domain. In layman's terms: enabling this feature for a domain makes a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers which are allowed to send e-mail messages from mail boxes using the domain. The moment this record propagates globally, it exists on all DNS servers that direct the Internet traffic. Every time an e-mail message is sent, the first DNS server it goes through tests if it comes from an official server. If it does, it is sent to the destination address, but when it does not originate from a server indexed in the SPF record for the domain, it is discarded. Thus nobody will mask an e-mail address then make it appear as if you're e-mailing spam. This technique is also called email spoofing.
SPF Protection in Cloud Hosting
You are able to activate the SPF protection option for your domains with a couple of clicks from the Hepsia Control Panel, which is included with all our cloud hosting. This is done via the section with an identical name and you can allow the protection for any domain hosted on our exceptional cloud hosting platform. Using a really handy interface, all you'll have to type in is the hostname of the mail server that will be authorized to send out messages from your email addresses and its IPv4 or IPv6 address. Of course, you're able to add several servers too, if needed. When your emails are taken care of on our end, you can also employ a more risk-free option by placing a restriction that emails can be sent only when your domains feature our MX records. This solution cannot be used if your web site is here, while the e-mails are with some third-party service provider. Either way, the SPF protection option will definitely improve your web security and prevent other people from counterfeiting your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account with us, you will be able to secure your email addresses by enabling the SPF security service for any domain in the account with just a couple of clicks. You can do this from the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even if you have no previous experience with these issues, you will not have any difficulties to activate the protection. Everything that you will have to do is to choose a domain name from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your e-mail addresses will be delivered globally only if they're sent from that server. When your e-mail addresses are managed by our company and not by a third-party provider, you will also be able to activate an option for e-mail messages to be sent only when the domain name has our MX records and the aforementioned would be the most secure option.
