Sender Policy Framework, or SPF, is a verification system, which is used to stop the so-called email spoofing where an email message is sent from one email, but to seem as being sent from another one, generally with the purpose to scam the recipient someway. When SPF protection is activated for a domain, a unique record is created for it in the Domain Name System and all DNS servers globally receive it. The record features all of the email servers that are permitted to send legitimate messages from an e-mail address under 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 target receiver. In case, however, the sending server is not present in the SPF record for the particular domain, the e-mail message won't be sent and it will be removed. In case you employ this solution, it'll prevent 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 domains in a shared hosting account with us and we manage the emails for them, you are able to activate SPF protection for all of them with a couple of clicks in your Hepsia Control Panel. This service is available in a separate section where you'll be able to view which domain names are already secured. For those which aren't, you can activate the SPF protection service and set up a variety of things in the process - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, and to set a rule that email messages can be sent only when your domains use our MX records. The last mentioned option is the most secure one, but you can use it when we handle the e-mails for your domains and you are not using a different e-mail provider. The newly generated records will be activated within a day and nobody will be able to forge the FROM field in an email by using your e-mail addresses.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account from us, you will be able to protect your emails by activating the SPF protection service for every domain in the account with just a couple of clicks. You can do this in the Emails section of the Hepsia Control Panel which is provided with the semi-dedicated accounts and even when you have no previous experience with such issues, you won't have any problems to enable the security. Everything that you'll need to do is to select a domain from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your email addresses will be mailed globally only if they're sent from that particular server. In case your email addresses are managed by us and not by some third-party supplier, you will also be able to activate an option for emails to be sent only if the domain 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.
