SPF, which means Sender Policy Framework, is an email security system, which is employed to validate if an email message is sent by an authorized server. Using SPF protection for a domain name will stop the faking of email addresses generated with the domain. In layman's terms: enabling this function for a domain name makes a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers which are permitted to send e-mails from mail boxes using the domain. When this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. Whenever a new email message is sent, the initial DNS server it goes through tests if it comes from an approved server. In the event it does, it is forwarded to the destination address, but when it doesn't come from a server indexed in the SPF record for the particular domain, it's discarded. Thus nobody will mask an email address then make it look as if you're e-mailing spam messages. This approach is also identified as email spoofing.

SPF Protection in Shared Hosting

If you host your domains in a shared hosting account on our end and we handle the e-mail addresses for them, you are able to enable SPF protection for any of them with a couple of clicks inside your Hepsia Control Panel. The service can be found in a separate section where you can see which domains are currently protected. For those that aren't, you will be able to enable the SPF protection solution and manage numerous things in the process - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, and to set a rule that email messages can be sent only when your domain names use our MX records. The aforementioned option is the most secure one, but you can use it when we take care of the email addresses for your domains and you are not using another e-mail service provider. The newly generated records will be activated within 24 hours and nobody will be able to forge the FROM field in a message by using your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account from our company, you will be able to protect your emails by activating the SPF protection service for every domain name hosted in the account with only a few mouse-clicks. This is done from the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even if you have no previous experience with such issues, you won't have any kind of trouble to enable the protection. All that you'll have 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. When the updated record propagates, messages from your e-mail addresses will be delivered worldwide only if they were sent from that server. In case your e-mail addresses are taken care of by our company and not by a third-party supplier, you will also be able to benefit from an option for e-mail messages to be mailed only if the domain includes our MX records and this is the most secure option. Should you have any kind of questions regarding thisfunction, you will be able to get in touch with our technical support crew 24/7.
