Sender Policy Framework, or SPF, is a verification system, which is used to prevent the so-called e-mail spoofing where an email message is sent from one email address, but to look as being sent from another one, frequently with the idea to scam the recipient someway. If SPF protection is enabled for a domain, a unique record is generated for it in the Domain Name System and all DNS servers globally get it. The record contains all the mail servers that are allowed to send authentic messages from an address under the domain. When an e-mail is sent, the first DNS server it encounters verifies the SPF record and when the sending server is permitted, the message is sent to the targeted receiver. When, however, the sending server is not contained in the SPF record for the specified domain, the email message will not be submitted and it will be removed. Whenever you employ this solution, it'll prevent third parties from sending spam e-mails that appear to have been sent by you.
SPF Protection in Shared Hosting
When you host your domains in a shared hosting account on our end and we manage the e-mails for them, you'll be able to activate SPF protection for all of them with several clicks inside your Hepsia Control Panel. This service is accessible in a separate section where you will be able to view which domains are already protected. For the ones that aren't, you will be able to enable the SPF protection option and manage a variety of things during this process - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and even to set a rule that email messages can be sent only when your domains include our MX records. The last mentioned solution is the most secure one, but it can be used if we manage the e-mails for your domain names and you're not using a different email service provider. The new records will be activated within 24 hours and nobody will be able to forge the FROM field in an e-mail by using your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from our company, you can protect your emails by enabling the SPF protection service for any domain name in your account with only a few mouse-clicks. This is done through the Emails section of the Hepsia Control Panel which is provided with the semi-dedicated accounts and even when you have no previous practical experience with such issues, you will not have any troubles to enable the protection. All that you'll need to do will be to find a domain name 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 sent globally only if they are sent from that particular server. In case your e-mail addresses are managed by our company and not by some third-party provider, you'll also be able to benefit from an option for emails to be mailed only when the domain features our MX records and the latter would be the safest option. When you have any kind of questions regarding thisfunction, you can contact our technical support crew 24/7.
