Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called email spoofing where an e-mail message is sent from one e-mail, but to appear as being sent from another one, generally with the idea to fraud the recipient in some way. If SPF protection is activated for a domain name, a unique record is created for it in the Domain Name System and all DNS servers around the world have it. The record contains all e-mail servers that are allowed to send legitimate messages from an e-mail address part of the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and in case its sending server is authorized, the message is sent to the targeted destination. When, however, the sending server doesn't exist in the SPF record for the specified domain, the email message won't be sent and it'll be discarded. In the event that you employ this service, it'll stop third parties from sending spam which appear to 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 manage the email addresses for them, you'll be able to activate SPF protection for them with a couple of clicks in your Hepsia Control Panel. This service is accessible in a separate section where you are able to view which domain names are already protected. For those that are not, you will be able to activate the SPF protection solution and manage a variety of things at the same time - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of these servers, as well as to set a rule that emails can be sent only if your domain names have our MX records. The last solution is the most secure one, and you can use it when we manage the emails for your domains and do not use some other e-mail service provider. The newly generated records will propagate within 1 day and nobody will be able to forge the FROM field in an email using your addresses.

SPF Protection in Semi-dedicated Hosting

When you have a semi-dedicated server account from us, you'll be able to secure your emails by activating the SPF protection service for every domain name in the account with only a couple of mouse-clicks. You can do this from the Emails section of our Hepsia Control Panel that is provided with the semi-dedicated accounts and even in case you have no previous practical experience with such things, you will not have any problems to activate the security. The only things that you'll need to do will be to select a domain name from a drop-down list then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be sent around the world only if they are sent from that particular server. If your email addresses are handled by us and not by some third-party supplier, you can also benefit from an option for email messages to be sent only if the domain name contains our MX records and the latter is the most secure option. When you have any kind of questions about thisfeature, you will be able to get in touch with our tech support crew 24/7.
