Sender Policy Framework, or SPF, is a verification system, which is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one email, but to appear as being sent from a different, frequently with the idea to fraud the recipient in some way. When SPF protection is enabled for a domain name, a specific record is made for it in the Domain Name System and all DNS servers around the world receive it. The record includes all the email servers that are permitted to send valid messages from an address part of the domain. When a message is sent, the first DNS server it encounters verifies the SPF record and in case the sending server is authorized, the message is sent to the target receiver. If, however, the sending server is not included in the SPF record for the specified domain, the e-mail message will not be sent and it will be discarded. When you employ this solution, it will prevent third parties from sending spam emails which appear to have been sent from you.
SPF Protection in Shared Hosting
SPF protection can be enabled for each domain hosted in a shared hosting account on our cloud platform with no more than a few mouse-clicks. The feature is available in the Emails section of our leading-edge Hepsia Control Panel and what is needed to enable it is to select one of your domains from a drop-down menu and type in the hostnames plus the IPv4 or IPv6 addresses of the e-mail servers that will be approved to send emails from your email addresses. As an additional option you can also restrict the e-mails to be sent from your domain only when it includes our MX records, i.e. if our servers manage the email addresses for it, not a third-party supplier. This feature will provide you with the highest degree of security, but it's not applicable in case only your web site is on our servers while the email addresses for the domain are taken care of elsewhere. In either case, our SPF protection service will keep your emails safe from being used for spam and/or scam purposes.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account with us, you can protect your email addresses by enabling the SPF protection service for any domain hosted in the 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 when you have no previous practical experience with these kinds of matters, you will not have any troubles to enable the security. The only things that you will have to do is to pick a domain from a drop-down list then type in the mail server hostname and IPv4 or IPv6 address. When the new record propagates, messages from your e-mail addresses will be sent worldwide only if they're sent from that particular server. When your e-mail addresses are managed by us and not by a third-party provider, you can also take advantage of an option for emails to be sent only when the domain includes our MX records and this is the most secure option. If you have any kind of questions about thisfeature, you'll be able to get in touch with our tech support crew 24/7.
