Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called e-mail spoofing where an email message can be sent from one e-mail address, but to look as being sent from another one, generally with the purpose to fraud the recipient someway. If SPF protection is activated for a domain name, a special record is created for it in the Domain Name System and all DNS servers globally have it. The record features all the e-mail servers that are permitted to send authentic messages from an e-mail address part of the domain. When an email is sent, the very first DNS server it goes to verifies the SPF record and when the sending server is authorized, the message is forwarded to the target receiver. When, however, the sending server is not contained in the SPF record for the given domain, the email message will not be submitted and it will be removed. Whenever you employ this service, it'll stop third parties from sending spam e-mails that appear to have been sent by you.
SPF Protection in Shared Hosting
You're able to enable the SPF protection service for your domain names with just a couple of clicks in the Hepsia Control Panel, which is included with all our shared hosting plans. This carried out from the section bearing the same name and you're able to allow the protection for any domain on our innovative cloud platform. Using a really simple interface, all you will need to submit is the hostname of the mail server which will be authorized to send out messages from your e-mails and its IPv4 or IPv6 address. Of course, you can add several servers as well, when needed. If your emails are managed by us, you may also use a more secure option by putting a restriction that emails can be sent only if your domain names have our MX records. This solution cannot be applied when your site is hosted with us, but your email addresses are with some third-party provider. In either case, the SPF protection option can vastly increase your online safety and prevent other people from forging your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from us, you'll be able to secure your email addresses by enabling the SPF protection service for every domain name in your account with only a few clicks. This is done from the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even when you have no previous experience with such issues, you won't have any trouble to enable the protection. All that you will have to do will be to find a domain from a drop-down list and after that type the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your email addresses will be delivered worldwide only if they are sent from that particular server. When your e-mail addresses are managed by our company and not by some third-party supplier, you'll also be able to benefit from an option for email messages to be sent only if the domain includes our MX records and the aforementioned would be the safest option.
