Sender Policy Framework, or SPF, is a verification system, that is employed to stop the so-called e-mail spoofing where an email message is sent from one e-mail address, but to look as being sent from another, typically with the objective to fraud the recipient someway. When SPF protection is enabled for a domain name, a unique record is generated for it in the Domain Name System and all of the DNS servers globally receive it. The record contains all the e-mail servers that are permitted to send legitimate messages from an e-mail address within the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and when the sending server is permitted, the message is forwarded to the targeted destination. When, however, the sending server is not present in the SPF record for the given domain, the message will not be forwarded and it'll be removed. Whenever you use this solution, it'll prevent third parties from sending spam messages that seem to have been sent by you.
SPF Protection in Cloud Hosting
If you host your domain names in a cloud hosting account on our end and we handle the email addresses for them, you will be able to enable SPF protection for all of them with a few clicks in your Hepsia Control Panel. This service is available in a separate section where you'll be able to see which domains are already protected. For the ones that aren't, you can activate the SPF protection option and set up a variety of things during this process - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and to set a rule that emails can be sent only when your domains have our MX records. The last mentioned choice is the most secure one, and it can be used when we manage the emails for your domains and you're not using a different email provider. The newly generated records will propagate within one day and nobody will be able to fake the FROM field in an email by using your email addresses.
SPF Protection in Semi-dedicated Hosting
The Hepsia website hosting Control Panel, which is provided with all of our Linux semi-dedicated hosting packages, provides you with an exceptionally easy-to-use interface to enable the SPF protection service for every domain that you host inside your new account. Several clicks in the Emails section of Hepsia will be enough for that then you'll only have to type in the hostname and the IP address of the mail server which will be allowed to send out messages from your e-mails. In case the e-mails are handled on our end and not by a different supplier, you will be able to increase the protection level even further and enable an option for all of the outgoing e-mail messages to be sent only if your domain names use our MX records. This option gives you more control and it will eliminate any possibility of anybody counterfeiting your email addresses with the purpose of spamming and scamming people. It is not applicable if just your website is on our outstanding cloud hosting platform, while your e-mail addresses are managed by a different provider. If you are not sure what features to pick, our technical support team will assist you 24/7.
