Sender Policy Framework, or SPF, is a verification system, which is intended to prevent the so-called e-mail spoofing where an email message is sent from one e-mail, but to look as being sent from another one, usually with the objective to fraud the recipient in some way. When SPF protection is activated for a domain, a special record is made for it in the Domain Name System and all of the DNS servers around the world have it. The record features all e-mail servers that are allowed to send valid messages from an address part of the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and when its sending server is permitted, the message is sent to the targeted receiver. When, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message will not be submitted and it will be removed. Whenever you use this service, it will prevent third parties from sending spam emails that seem to have been sent from you.
SPF Protection in Shared Website Hosting
You'll be able to activate the SPF protection option for your domains with just a couple of clicks from the Hepsia Control Panel, which is provided with all of our Linux shared website hosting services. This is performed from the section with an identical name and you'll be able to enable the protection for each and every domain hosted on our revolutionary cloud hosting platform. Using a very intuitive interface, all you have to type in is the hostname of the mail server that will be authorized to send messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, you're able to add several servers as well, if needed. In case your e-mails are managed on our end, you may also use a more risk-free option by putting a restriction that emails can be sent only if your domains have our MX records. This solution cannot be applied when your website is hosted here, and your email addresses are with some third-party supplier. In either case, the SPF protection solution will significantly improve your online safety and prevent others from counterfeiting your email addresses.
SPF Protection in Semi-dedicated Hosting
If you have a semi-dedicated server account from our company, you can protect your email addresses by activating the SPF protection service for any domain name in your account with only a couple of clicks. You can do this from the Emails section of the Hepsia Control Panel which is provided with the semi-dedicated accounts and even if you lack previous experience with these matters, you will not have any troubles to activate the security. All that you will need to do is to select a domain name from a drop-down list then type the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your e-mail addresses will be sent globally only if they are sent from that specific server. In case your emails are taken care of by our company and not by some third-party supplier, you'll also be able to benefit from an option for email messages to be mailed only when the domain features our MX records and this is the safest option.
