Sender Policy Framework, or SPF, is a verification system, which is used to prevent the so-called email spoofing where an e-mail message can be sent from one e-mail, but to look as being sent from a different one, often with the purpose to fraud the recipient for some reason. If SPF protection is enabled for a domain, a specific record is generated for it in the Domain Name System and all DNS servers around the world get it. The record includes all e-mail servers that are permitted to send authentic messages from an address within the domain. When an e-mail is sent, the first DNS server it encounters verifies the SPF record and if the sending server is authorized, the message is forwarded to the target destination. When, however, the sending server is not present in the SPF record for the particular domain, the email message will not be forwarded and it'll be removed. If you use this solution, it will stop third parties from sending spam messages that look as if they have been sent by you.

SPF Protection in Cloud Website Hosting

When you host your domains in a cloud website hosting account on our end and we manage the e-mail addresses for them, you'll be able to enable SPF protection for them with a couple of clicks inside your Hepsia Control Panel. The service can be found in a section of its own where you're able to view which domain names are currently secured. For those that aren't, you'll be able to enable the SPF protection option and manage numerous things during the process - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and even to create a rule that messages can be sent only when your domain names include our MX records. The last choice is the most secure one, and it can be used if we manage the email addresses for your domains and you're not using a different e-mail supplier. The newly created records will be activated within 24 hours and nobody will be able to fake the FROM field in an email 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 activating the SPF security service for any domain hosted in the account with just a few mouse-clicks. This is done in the Emails section of the Hepsia Control Panel which comes with the semi-dedicated accounts and even when you have no previous practical experience with these kinds of matters, you will not have any kind of difficulties to enable the security. The only things that you will have to do is to pick a domain from a drop-down menu and after that type in the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your emails will be sent around the world only if they are sent from that specific server. In case your e-mail addresses are handled by our company and not by some third-party supplier, you can also take advantage of an option for emails to be mailed only if the domain includes our MX records and the aforementioned is the most secure option. In case you have any kind of questions regarding thisfeature, you will be able to get in touch with our technical support crew 24/7.
