Sender Policy Framework, or SPF, is a validation system, that is employed to stop the so-called email spoofing where an e-mail message is sent from one email address, but to appear as being sent from a different, often with the idea to scam the recipient someway. If SPF protection is activated for a domain name, an exclusive record is made for it in the Domain Name System and all the DNS servers globally get it. The record features all of the email servers that are permitted to send authentic messages from an address within the domain. When an email is sent, the first DNS server it encounters checks the SPF record and if its sending server is authorized, the message is forwarded to the targeted destination. When, however, the sending server is not contained in the SPF record for the particular domain, the e-mail message won't be forwarded and it'll be removed. In case you employ this service, it will prevent third parties from sending spam messages which seem to have been sent by you.

SPF Protection in Shared Website Hosting

You'll be able to enable the SPF protection service for your domains with only a few clicks from the Hepsia Control Panel, which is included with our shared website hosting plans. This carried out through the section bearing the same name and you are able to enable the protection for each domain hosted on our advanced cloud platform. Using a really intuitive interface, all you will have to type in is the hostname of the mail server which will be authorized to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you are able to add several servers too, if needed. If your e-mail addresses are taken care of on our end, you may also take advantage of an even more secure option by placing a limit that e-mail messages can be sent only when your domain names feature our MX records. This option cannot be used if your site is hosted here, but the e-mails are with some third-party provider. In either case, the SPF protection option will vastly enhance your online protection and stop other people from forging your e-mail addresses.
