Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called email spoofing where an e-mail message is sent from one address, but to seem as being sent from another, frequently with the idea to scam the recipient for some reason. If SPF protection is enabled for a domain name, a unique record is created for it in the Domain Name System and all the DNS servers around the world have it. The record includes all mail servers that are permitted to send authentic messages from an address within the domain. When a message is sent, the first DNS server it encounters checks the SPF record and when the sending server is permitted, the message is sent to the target destination. When, however, the sending server is not included in the SPF record for the particular domain, the message won't be submitted and it will be removed. In the event that you use this service, it will prevent third parties from sending spam which seem to have been sent from you.

SPF Protection in Hosting

You are able to enable the SPF protection service for your domains with only a couple of clicks in the Hepsia Control Panel, which is included with all our Linux hosting packages. This is done through the section with the same name and you can set up the protection for each and every domain name on our modern cloud hosting platform. Using a really time and effort saving interface, all you'll need to enter is the hostname of the mail server that will be authorized to send out messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you are able to include several servers as well, when needed. When your e-mail addresses are managed on our end, you may also employ a more secure option by setting a restriction that emails can be sent only when your domains include our MX records. This option can't be applied in case your website is hosted with us, but your e-mail addresses are with some third-party supplier. In either case, the SPF protection solution will vastly increase your web safety and prevent other people from counterfeiting your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account from our company, you are able to secure your email addresses by enabling the SPF protection service for any domain name in your account with just a couple of clicks. This is done in the Emails section of our Hepsia Control Panel which comes with the semi-dedicated accounts and even when you have no previous experience with these matters, you won't have any difficulties to enable the security. Everything that you will need to do is to choose a domain from a drop-down menu then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your emails will be sent around the world only if they're sent from that server. If your emails are managed by us and not by a third-party supplier, you can also activate an option for e-mail messages to be mailed only when the domain name features our MX records and the latter is the safest option. Should you have any kind of questions related to thisfunction, you'll be able to contact our support crew 24/7.
