Sender Policy Framework, or SPF, is a validation system, which is employed to prevent the so-called email spoofing where an email message can be sent from one email, but to appear as being sent from another one, generally with the purpose to scam the recipient in some way. When SPF protection is activated for a domain name, a unique record is generated for it in the Domain Name System and all DNS servers around the world receive it. The record contains all of the e-mail servers that are allowed to send legitimate messages from an email address part of the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and if the sending server is permitted, the message is forwarded to the target receiver. If, however, the sending server is not contained in the SPF record for the given domain, the email message will not be sent and it will be discarded. In case you employ this service, it'll stop third parties from sending spam e-mails that look as if they have been sent from you.

SPF Protection in Shared Hosting

When you host your domain names in a shared hosting account with us and we handle the email addresses for them, you are able to activate SPF protection for all of them with a few clicks inside your Hepsia Control Panel. This service is accessible in its own section where you're able to view which domain names are currently secured. For the ones which aren't, you will be able to activate the SPF protection solution and configure a number of things during this process - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, as well as to create a rule that email messages can be sent only if your domains include our MX records. The last choice is the most secure one, but it can be used if we take care of the email addresses for your domains and you are not using some other email service provider. The new records will propagate within a day and nobody will be able to fake the FROM field in an e-mail by using your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

When you have a semi-dedicated server account from our company, you are able to protect your emails by enabling the SPF protection service for every domain in your account with just a few clicks. This is done from 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 issues, you won't have any difficulties to activate the protection. Everything that you'll need to do will be to choose a domain name from a drop-down menu and after that type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your email addresses will be sent around the world only if they are sent from that particular server. In case your emails are handled by our company and not by a third-party supplier, you can also take advantage of an option for email messages to be sent only when the domain name contains our MX records and the aforementioned is the most secure option. Should you have any questions about thisfunction, you can contact our technical support crew 24/7.
