Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called email spoofing where an email message can be sent from one email address, but to look as being sent from another, typically with the idea to fraud the recipient for some reason. When SPF protection is enabled for a domain name, a specific record is created for it in the Domain Name System and all DNS servers worldwide receive it. The record features all mail servers that are allowed to send legitimate messages from an address within the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and when its sending server is permitted, the message is forwarded to the target receiver. When, however, the sending server doesn't exist in the SPF record for the specified domain, the e-mail message will not be submitted and it'll be removed. When you employ this solution, it'll prevent third parties from sending spam e-mails which look as if they have been sent by you.
SPF Protection in Cloud Website Hosting
You can activate the SPF protection option for your domain names with just a few clicks inside the Hepsia Control Panel, which is included with all of our cloud website hosting plans. This carried out through the section with the same name and you'll be able to allow the protection for each domain name on our modern cloud hosting platform. Using a very user-friendly interface, all you need to enter is the hostname of the mail server that will be authorized to send messages from your e-mails and its IPv4 or IPv6 address. Of course, you can add several servers as well, if needed. When your e-mails are handled by us, you can also use an even more risk-free option by setting a limit that messages can be sent only when your domains feature our MX records. This alternative can't be used in case your site is hosted with us, and your email addresses are with some third-party supplier. In either case, the SPF protection solution can strongly increase your web protection and stop others from spoofing 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 emails by activating the SPF protection service for every domain name hosted in the account with only a couple of mouse-clicks. This is done in the Emails section of our Hepsia Control Panel which is provided with the semi-dedicated accounts and even if you have no previous practical experience with these kinds of things, you will not have any difficulties to activate the security. Everything that you will need to do will be to pick a domain name from a drop-down list then type in the mail server hostname and IPv4 or IPv6 address. When the new record propagates, messages from your e-mail addresses will be sent globally only if they were sent from that server. When your emails are taken care of by our company and not by a third-party supplier, you will also be able to use an option for e-mail messages to be mailed only when the domain includes our MX records and this is the safest option. Should you have any questions regarding thisfunction, you will be able to contact our tech support crew 24/7.
