Sender Policy Framework, or SPF, is a verification system, which is designed to stop the so-called e-mail spoofing where an e-mail message is sent from one e-mail address, but to seem as being sent from a different one, typically with the objective to fraud the recipient in some way. When SPF protection is enabled for a domain name, an exclusive record is created for it in the Domain Name System and all of the DNS servers around the world get it. The record contains all the email servers that are permitted to send valid messages from an address under the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and if the sending server is authorized, the message is forwarded to the targeted destination. In case, however, the sending server is not included in the SPF record for the given domain, the e-mail message will not be sent and it will be removed. When you use this service, it will stop third parties from sending spam messages that appear to have been sent by you.
SPF Protection in Cloud Web Hosting
When you host your domain names in a cloud web hosting account with us and we manage the e-mail addresses for them, you will be able to enable SPF protection for them with a few clicks in your Hepsia Control Panel. The service can be found in a separate section where you're able to view which domain names are already secured. For the ones that aren't, you'll be able to activate the SPF protection service and manage a number of things during the process - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, and even to set a rule that messages can be sent only when your domains have our MX records. The last mentioned solution is the most secure one, and it can be used in the event that we manage the email addresses for your domains and you are not using some other email service provider. The newly generated records will be activated within one day and nobody will be able to forge the FROM field in an e-mail with your addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from us, you are able to secure your emails by enabling the SPF security service for every domain name in your account with just a couple of clicks. This is done through the Emails section of the Hepsia Control Panel that is included with the semi-dedicated accounts and even if you lack previous practical experience with these kinds of issues, you will not have any kind of troubles to activate the protection. All that you will need to do is to find a domain from a drop-down list 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 delivered worldwide only if they were sent from that specific server. If your e-mail addresses are taken care of by our company and not by some third-party supplier, you can also activate an option for emails to be sent only if the domain includes our MX records and the aforementioned is the most secure option. In case you have any questions related to thisfeature, you will be able to contact our technical support team 24/7.
