SPF, which is short for Sender Policy Framework, is an email security system, that is is intended to confirm whether an email message was sent by a licensed server. Employing SPF protection for a particular domain name will stop the counterfeiting of email addresses made with the domain. In simple words: enabling this function for a domain makes a special record in the Domain Name System (DNS) containing the IP of the servers which are permitted to send e-mail messages from mail boxes using the domain. The moment this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. When some email message is sent, the first DNS server it goes through verifies whether it comes from an official server. If it does, it is sent to the destination address, however if it does not come from a server listed in the SPF record for the domain, it's discarded. Thus nobody will be able to mask an e-mail address then make it appear as if you're sending spam messages. This technique is also referred to as email spoofing.

SPF Protection in Web Hosting

You're able to activate the SPF protection option for your domains with only a couple of clicks inside the Hepsia Control Panel, which is included in all of our web hosting plans. This is performed through the section bearing an identical name and you'll be able to set up the protection for each and every domain name on our exceptional cloud hosting platform. Using a really handy interface, all you'll need to submit is the hostname of the mail server that will be accredited to send messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you can add several servers too, if needed. In case your e-mail addresses are handled by us, you may also take advantage of a more secure option by placing a limit that e-mail messages can be sent only when your domains have our MX records. This alternative cannot be applied in case your web site is hosted here, but the e-mails are with some third-party supplier. In either case, the SPF protection solution can definitely improve your web safety and stop other people from forging your e-mail addresses.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account from us, you will be able to secure your email addresses by activating the SPF security service for every domain in the account with just a couple of clicks. This is done in the Emails section of our Hepsia Control Panel that comes with the semi-dedicated accounts and even if you lack previous experience with these kinds of issues, you won't have any difficulties to activate the protection. Everything that you will have to do is to find a domain from a drop-down menu and after that type in the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your e-mail addresses will be mailed worldwide only if they are sent from that server. In case your e-mail addresses are managed by us and not by a third-party supplier, you can also use an option for e-mail messages to be sent only if the domain contains our MX records and the latter is the safest option. In case you have any kind of questions related to thisfunction, you will be able to contact our support crew 24/7.
