Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email, but to appear as being sent from another one, usually with the objective to scam the recipient for some reason. When SPF protection is enabled for a domain, an exclusive record is made for it in the Domain Name System and all of the DNS servers globally have it. The record includes all email servers that are allowed to send legitimate messages from an email address within the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and if the sending server is permitted, the message is forwarded to the target destination. In case, however, the sending server is not contained in the SPF record for the specified domain, the message will not be submitted and it will be discarded. Whenever you employ this service, it will prevent third parties from sending spam which look as if they have been sent by you.
SPF Protection in Shared Website Hosting
You're able to enable the SPF protection option for your domains with a few clicks from the Hepsia Control Panel, which is included in our shared website hosting service. This is done through the section bearing the same name and you are able to enable the protection for each and every domain on our cutting-edge cloud hosting platform. Using a really simple interface, all you will have to enter is the hostname of the mail server which will be authorized to send out messages from your email addresses and its IPv4 or IPv6 address. Of course, you can include several servers too, if needed. If your e-mails are taken care of by us, you can also use an even more risk-free option by placing a limit that e-mail messages can be sent only if your domain names feature our MX records. This alternative cannot be used if your web site is hosted with us, while the email addresses are with some third-party supplier. In either case, the SPF protection option can really improve your web 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 our company, you will be able to secure your emails by enabling the SPF protection service for any domain in your account with only a couple of clicks. This is done through the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even if you lack previous experience with such things, you won't have any kind of problems to activate the security. The only things that you'll have to do will be to find a domain name from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your e-mail addresses will be sent globally only if they are sent from that particular server. If your email addresses are taken care of by our company and not by a third-party provider, you can also activate an option for email messages to be mailed only if the domain name includes our MX records and this would be the safest option. If you have any kind of questions related to thisfeature, you will be able to get in touch with our support team 24/7.
