Sender Policy Framework, or SPF, is a verification system, that is intended to prevent the so-called e-mail spoofing where an email message is sent from one e-mail, but to look as being sent from another one, often with the idea to fraud the recipient for some reason. When SPF protection is activated for a domain, a special record is made for it in the Domain Name System and all DNS servers globally get it. The record contains all the mail servers that are permitted to send authentic messages from an email address within the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and when the sending server is authorized, the message is sent to the targeted destination. If, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message will not be forwarded and it will be removed. In the event that 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 Website Hosting
SPF protection can be enabled for each domain hosted in a shared website hosting account on our cloud hosting platform with just a few clicks. The option is accessible in the Emails section of our leading-edge Hepsia Control Panel and all you need to enable it is to choose one of your domain names from a drop-down menu and then enter the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers that will be permitted to send emails from your email addresses. As an additional option you may also restrict the e-mails to be sent from your domain only when it includes our MX records, i.e. when our servers handle the emails for it, not a third-party provider. This feature gives you the top level of protection, but it is not applicable if only your web site is on our servers while your emails for the domain are handled in another place. In either case, our SPF protection service will keep your emails secure from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
When you have a semi-dedicated server account from our company, you'll be able to secure your emails by activating the SPF protection service for every domain name hosted in your account with only a couple of clicks. You can do this through the Emails section of our Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you lack previous practical experience with these issues, you will not have any problems to activate the security. Everything that you will need to do is to pick a domain name from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your e-mail addresses will be sent globally only if they are sent from that specific server. When your emails are handled by our company and not by a third-party provider, you'll also be able to take advantage of an option for e-mail messages to be sent only when the domain has our MX records and the aforementioned would be the safest option.
