Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called email spoofing where an email message is sent from one address, but to seem as being sent from a different one, ordinarily with the objective to scam the recipient for some reason. If SPF protection is activated for a domain name, a unique record is created for it in the Domain Name System and all of the DNS servers around the world receive it. The record includes all mail servers that are allowed 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 if the 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 specified domain, the message won't be sent and it'll be discarded. If you use this solution, it'll stop third parties from sending spam messages that look as if they have been sent from you.

SPF Protection in Cloud Web Hosting

You can activate the SPF protection service for your domain names with a few clicks from the Hepsia Control Panel, which comes with all of our cloud web hosting. This carried out via the section bearing the same name and you can set up the protection for each and every domain hosted on our leading-edge cloud hosting platform. Using a very convenient interface, all you have to enter is the hostname of the mail server which will be permitted to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you can add several servers as well, if needed. When your e-mails are taken care of by us, you can also use an even more secure option by putting a restriction that e-mails can be sent only when your domains feature our MX records. This alternative can't be used if your site is here, and the e-mails are with a third-party service provider. In either case, the SPF protection option can really enhance your online security and prevent others from spoofing your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

When you have a semi-dedicated server account from our company, you are able to secure your email addresses by activating the SPF protection service for every domain name in your account with just a few mouse-clicks. This is done through the Emails section of our Hepsia Control Panel which is included with the semi-dedicated accounts and even in case you have no previous practical experience with these matters, you won't have any kind of difficulties to activate the protection. Everything that you'll need to do is to select a domain from a drop-down list and after that type in the mail server hostname and IPv4 or IPv6 address. When the new record propagates, messages from your e-mail addresses will be delivered globally only if they are sent from that specific server. If your emails are handled by us and not by a third-party supplier, you can also activate an option for e-mail messages to be sent only if the domain name includes our MX records and the latter would be the safest option.
