Sender Policy Framework, or SPF, is a verification system, which is used to stop the so-called e-mail spoofing where an e-mail message can be sent from one e-mail address, but to look as being sent from a different, usually with the objective to fraud the recipient for some reason. If SPF protection is activated for a domain name, an exclusive record is created for it in the Domain Name System and all of the DNS servers globally receive it. The record features all mail servers that are permitted to send valid messages from an email address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and in case the sending server is authorized, the message is forwarded to the targeted receiver. If, however, the sending server is not present in the SPF record for the particular domain, the message will not be forwarded and it will be removed. Whenever you employ this solution, it will stop third parties from sending spam emails that appear to have been sent by you.
SPF Protection in Cloud Web Hosting
If you host your domains in a cloud web hosting account on our end and we handle the e-mails for them, you'll be able to activate SPF protection for them with a couple of clicks in your Hepsia Control Panel. The service can be found in a section of its own where you can view which domains are already protected. For those that are not, you can activate the SPF protection option and configure a variety of things in the process - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and to set a rule that messages can be sent only when your domains have our MX records. The aforementioned choice is the most secure one, but you can use it if we handle the emails for your domain names and you are not using some other e-mail supplier. The newly generated records will propagate within 24 hours and nobody will be able to forge the FROM field in a message using your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from us, you are able to protect your emails by activating the SPF security service for every domain in your account with only a couple of clicks. You can do this from the Emails section of our Hepsia Control Panel which is provided with the semi-dedicated accounts and even when you have no previous experience with such things, you will not have any trouble to activate the protection. Everything that you will have to do is to choose a domain from a drop-down list then type in the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your email addresses will be mailed around the world only if they were sent from that particular server. If your emails are managed by our company and not by a third-party supplier, you can also benefit from an option for emails to be sent only when the domain contains our MX records and the aforementioned would be the most secure option. In case you have any kind of questions related to thisfeature, you can get in touch with our support crew 24/7.
