Sender Policy Framework, or SPF, is a validation system, that is intended to stop the so-called e-mail spoofing where an email message is sent from one email address, but to seem as being sent from another, generally with the idea to scam the recipient in some way. When SPF protection is activated for a domain name, a special record is made for it in the Domain Name System and all the DNS servers globally have it. The record includes all the e-mail servers that are allowed to send valid messages from an email address under the domain. When an e-mail is sent, the very first DNS server it goes to verifies the SPF record and if its sending server is permitted, the message is forwarded to the targeted destination. When, however, the sending server is not included in the SPF record for the specified domain, the email message won't be forwarded and it'll be removed. Whenever you use this solution, it'll prevent third parties from sending spam emails that seem to have been sent by you.
SPF Protection in Shared Hosting
If you host your domains in a shared hosting account on our end and we handle the emails for them, you will be able to enable SPF protection for any of them with a couple of clicks in your Hepsia Control Panel. This service can be found in its own section where you can view which domain names are already secured. For the ones that are not, you will be able to activate the SPF protection option and set up various things during the process - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and even to set a rule that messages can be sent only if your domain names have our MX records. The aforementioned choice is the most secure one, but you can use it in the event that we manage the e-mail addresses for your domains and do not use a different e-mail supplier. The newly created records will propagate 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
The SPF protection function is provided with all of the Linux semi-dedicated packages, so if you host your domains in an account on our cloud hosting platform, you're able to use the service without difficulty for all your domains. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, features a really easy to use interface, which means that you will not need to be proficient in the use of computers in order to protected your e-mail addresses. You will simply have to type the hostname and the IP of each mail server that you'd like to be permitted to send out e-mails from your addresses and right after that the new record will be active for the domain that you've chosen. As an additional option, we will also give you the ability to limit your outgoing email messages and protect your mailboxes further by permitting messages to be sent only when the domain name involved has our MX records i.e. the email messages for the domain have to be taken care of here and not by some other company. Doing so you'll have even better control and there won't be a chance for somebody to fake your emails for harmful purposes.
