Sender Policy Framework, or SPF, is a validation system, that is intended to stop the so-called email spoofing where an email message is sent from one address, but to appear as being sent from another one, often with the idea to scam the recipient someway. When SPF protection is enabled for a domain, a specific record is created for it in the Domain Name System and all the DNS servers around the world receive it. The record contains all the mail servers that are permitted to send authentic messages from an email address under the domain. When an email is sent, the very first DNS server it goes to verifies the SPF record and in case its sending server is permitted, the message is forwarded 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 forwarded and it will be removed. When you employ this solution, it will prevent third parties from sending spam messages which appear to have been sent by you.
SPF Protection in Shared Hosting
If you host your domain names in a shared hosting account on our end and we manage the e-mail addresses for them, you will be able to enable SPF protection for any of them with several clicks inside your Hepsia Control Panel. This service is accessible in a section of its own where you are able to see which domains are currently secured. For the ones that aren't, you can activate the SPF protection service and set up various things in the process - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and to create a rule that messages can be sent only when your domains have our MX records. The aforementioned choice is the most secure one, and you can use it in the event that we handle the emails for your domains and you are not using another email supplier. The new records will propagate within 24 hours and nobody will be able to forge the FROM field in a message by using your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
When you have a semi-dedicated server account with us, you are able to secure your emails by enabling the SPF protection service for any domain hosted in the account with only a few 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 have no previous experience with such matters, you will not have any kind of trouble to activate the protection. All that you'll have to do will be to pick a domain from a drop-down menu and then type in the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your email addresses will be delivered globally only if they're sent from that specific server. When your emails are handled by us and not by a third-party supplier, you can also benefit from an option for email messages to be mailed only if the domain name features our MX records and the latter would be the safest option. In case you have any questions about thisfeature, you can get in touch with our technical support crew 24/7.
