Sender Policy Framework, or SPF, is a verification system, which is employed to stop the so-called e-mail spoofing where an email message can be sent from one address, but to look as being sent from another one, usually with the idea to scam the recipient in some way. If SPF protection is enabled for a domain, a unique record is generated for it in the Domain Name System and all DNS servers globally receive it. The record features all mail servers that are allowed to send authentic messages from an email address within the domain. When a message is sent, the first DNS server it goes to verifies the SPF record and if 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 will not be submitted and it will be discarded. In case you use this solution, it'll prevent third parties from sending spam emails which appear to have been sent from you.
SPF Protection in Shared Website Hosting
If you host your domain names in a shared website hosting account with us and we handle the e-mails for them, you'll be able to activate SPF protection for all of them with several clicks inside your Hepsia Control Panel. This service can be found in a section of its own where you can see which domain names are currently protected. For the ones that are not, you'll be able to activate the SPF protection solution and manage a lot of things during this process - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that email messages can be sent only if your domain names include our MX records. The aforementioned choice is the most secure one, but you can use it when we take care of the email addresses for your domain names and you're not using a different e-mail supplier. The new records will be activated within a day and nobody will be able to forge 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 with us, you can protect your emails by enabling the SPF security service for any domain hosted in your account with just a couple of clicks. This can be done through the Emails section of the Hepsia Control Panel which is provided with the semi-dedicated accounts and even in case you have no previous practical experience with these things, you won't have any difficulties to activate the security. Everything that you will have to do is to pick a domain name from a drop-down list and after that type in the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your email addresses will be delivered globally only if they're sent from that server. If your e-mail addresses 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 emails to be sent only if the domain features our MX records and this would be the safest option. Should you have any questions regarding thisfunction, you will be able to contact our technical support crew 24/7.
