Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called e-mail spoofing where an email message can be sent from one email, but to appear as being sent from another one, generally with the objective to fraud the recipient someway. If SPF protection is activated for a domain name, an exclusive record is generated for it in the Domain Name System and all the DNS servers around the world have it. The record includes all the e-mail servers that are permitted to send valid messages from an address under the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and in case the sending server is permitted, the message is sent to the targeted destination. In case, however, the sending server is not present in the SPF record for the given domain, the email message won't be submitted and it will be discarded. In case you employ this solution, it will stop third parties from sending spam emails that look as if they have been sent by you.
SPF Protection in Shared Website Hosting
SPF protection can be activated for every domain hosted in a shared website hosting account on our cloud platform with only a couple of clicks. The option is available in the Emails section of our state-of-the-art Hepsia Control Panel and all it takes to enable it is to choose one of your domains from the drop-down menu and then type in the hostnames as well as the IPv4 or IPv6 addresses of the mail servers which will be permitted to send email messages from your email addresses. As an additional option you may also restrict the e-mails to be sent from your domain name only when it includes our MX records, in other words when our servers handle the e-mail addresses for it, not a third-party supplier. This solution offers you the best degree of security, but it is not applicable when only your website is on our servers while your email addresses for the domain are managed elsewhere. Either way, our SPF protection service will keep your email addresses protected from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
The Hepsia web hosting Control Panel, which comes with our Linux semi-dedicated hosting packages, provides you with an incredibly user-friendly interface to activate the SPF protection service for every domain that you host inside your new account. Just a few clicks in the Emails section of Hepsia are enough for that and you'll only have to type in the hostname and the IP address of the mail server which will be allowed to send out messages from your emails. If the emails are managed by us and not by another provider, you'll be able to raise the security level even more and enable an option for the outgoing e-mail messages to be sent only if your domains use our MX records. This option provides you with more control and it will eliminate any chance of somebody counterfeiting your email addresses with the purpose of spamming and / or scamming people. It is not applicable if just your site is on our advanced cloud website hosting platform, while your emails are managed by a different service provider. If you are not sure what features to choose, our technical support crew will help you 24/7.
