Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called email spoofing where an email message can be sent from one email, but to look as being sent from a different, usually with the objective to fraud the recipient for some reason. When SPF protection is enabled for a domain name, a specific record is made for it in the Domain Name System and all DNS servers around the world have it. The record includes all the email servers that are allowed to send legitimate messages from an e-mail address part of the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and if its sending server is permitted, the message is sent to the target destination. In case, however, the sending server is not contained in the SPF record for the particular domain, the message will not be forwarded and it will be removed. When you use this service, it'll stop third parties from sending spam emails that seem to have been sent from you.
SPF Protection in Cloud Hosting
You're able to enable the SPF protection service for your domain names with only a couple of clicks inside the Hepsia Control Panel, which is included in all our Linux cloud packages. This is done via the section bearing the same name and you are able to enable the protection for any domain part of our outstanding cloud platform. Using a very user-friendly interface, all you have to enter is the hostname of the mail server which will be authorized to send out messages from your emails and its IPv4 or IPv6 address. Last, but not least, you can include several servers too, if needed. If your e-mails are taken care of on our end, you can also employ an even more risk-free option by placing a limit that messages can be sent only if your domain names have our MX records. This solution can't be applied in case your website is hosted here, while the email addresses are with a third-party supplier. In either case, the SPF protection solution will significantly increase your online protection and stop other people from spoofing your email addresses.
SPF Protection in Semi-dedicated Hosting
When you have a semi-dedicated server account with us, you will be able to protect your email addresses by enabling the SPF security service for every domain in your account with only a few clicks. This can be done from the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even in case you have no previous practical experience with these kinds of things, you won't have any kind of trouble to enable the protection. Everything that you'll need to do will be to find a domain from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. Once the new record propagates, messages from your email addresses will be delivered around the world only if they're sent from that specific server. In case your e-mail addresses are taken care of by our company and not by a third-party provider, you'll also be able to take advantage of an option for emails to be mailed only when the domain name contains our MX records and the aforementioned would be the most secure option. When you have any kind of questions regarding thisfunction, you'll be able to contact our technical support crew 24/7.
