Sender Policy Framework, or SPF, is a verification system, which is employed to prevent the so-called email spoofing where an e-mail message is sent from one email address, but to seem as being sent from another one, often with the objective to fraud the recipient for some reason. When SPF protection is enabled for a domain name, a special record is created for it in the Domain Name System and all DNS servers worldwide have it. The record contains all the e-mail servers that are allowed to send valid messages from an email address under the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and in case its sending server is authorized, the message is sent to the targeted destination. When, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message won't be submitted and it'll be removed. Whenever you employ this service, it'll stop third parties from sending spam which look as if they have been sent by you.
SPF Protection in Shared Website Hosting
When you host your domain names in a shared website hosting account on our end and we handle the email addresses for them, you are able to enable SPF protection for any of them with a few clicks inside your Hepsia Control Panel. This service is accessible in a section of its own where you will be able to view which domains are already secured. For those which aren't, you'll be able to activate the SPF protection solution and configure a lot of things during this process - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, and to create a rule that messages can be sent only when your domains use our MX records. The aforementioned solution is the most secure one, but it can be used when we take care of the emails for your domain names and do not use a different e-mail provider. The newly generated records will be activated within a day and nobody will be able to forge the FROM field in an e-mail by using your addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from us, you'll be able to secure your email addresses by enabling the SPF security service for every domain hosted in your account with just a couple of clicks. You can do this through the Emails section of the Hepsia Control Panel that is included with the semi-dedicated accounts and even in case you have no previous experience with such issues, you will not have any troubles to enable the security. Everything that you will have to do is to find a domain name from a drop-down list and after that type in the mail server hostname and IPv4 or IPv6 address. Once the new record propagates, messages from your email addresses will be sent around the world only if they're sent from that specific server. If your e-mail addresses are handled by our company and not by some third-party provider, you'll also be able to use an option for email messages to be sent only when the domain has our MX records and the aforementioned would be the most secure option. When you have any kind of questions about thisfeature, you will be able to get in touch with our technical support crew 24/7.
