Sender Policy Framework, or SPF, is a verification system, that is intended to stop the so-called email spoofing where an e-mail message can be sent from one email, but to appear as being sent from another one, typically with the purpose to scam the recipient for some reason. When SPF protection is enabled for a domain, a special record is generated for it in the Domain Name System and all DNS servers globally have it. The record features all the e-mail servers that are permitted to send legitimate messages from an email address within the domain. When an email is sent, the very first DNS server it encounters verifies the SPF record and in case the sending server is authorized, the message is forwarded to the target receiver. When, however, the sending server is not present in the SPF record for the particular domain, the message won't be submitted and it'll be removed. In case you use this solution, it'll stop third parties from sending spam emails that seem to have been sent by you.
SPF Protection in Shared Web Hosting
If you host your domains in a shared web hosting account with us and we manage the e-mail addresses for them, you will be able to enable SPF protection for all of them with several clicks inside your Hepsia Control Panel. The service is available in a section of its own where you're able to see which domains are currently secured. For those which aren't, you will be able to activate the SPF protection service and set up various things during this process - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that messages can be sent only if your domains include our MX records. The last choice is the most secure one, and you can use it when we take care of the emails for your domain names and do not use a different e-mail service provider. The newly generated records will be activated within a day and nobody will be able to fake the FROM field in an email by using your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
The SPF protection feature comes with all of the Linux semi-dedicated hosting, so in case you host your domain names in an account on our cloud web hosting platform, you'll be able to use this service without difficulty for all of your domains. The Hepsia Control Panel, which is included with the semi-dedicated accounts, has a very easy to use interface, so you don't have to be proficient in the use of computers in order to secure your e-mails. You'll only have to type the hostname and the IP of each mail server that you would like to be certified to send e-mails from your addresses and right after that the updated record will be active for the domain that you've chosen. As a further option, we will also allow you to restrict the outgoing emails and secure your mailboxes even further by allowing email messages to be sent only if the domain name in question includes our MX records i.e. the email messages for the domain name have to be managed here and not by some other supplier. In this way you'll enjoy even superior control and there will not be any chance for someone to fake your e-mail addresses for harmful activities.
