Sender Policy Framework, or SPF, is a verification system, which is used to stop the so-called e-mail spoofing where an e-mail message can be sent from one email address, but to appear as being sent from a different, usually with the purpose to fraud the recipient for some reason. When SPF protection is enabled for a domain name, a special record is generated for it in the Domain Name System and all of the DNS servers worldwide have it. The record features all the mail servers that are allowed to send valid messages from an e-mail address under the domain. When a message is sent, the first DNS server it encounters verifies 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 e-mail message won't be submitted and it will be discarded. In case you employ this service, it will prevent third parties from sending spam which seem to have been sent by you.
SPF Protection in Web Hosting
SPF protection can be enabled for every domain hosted in a web hosting account on our cloud hosting platform with just a couple of clicks. The function is available in the Emails section of our modern Hepsia Control Panel and all it takes to enable it is to pick one of your domain names from the drop-down menu and then enter the hostnames together with the IPv4 or IPv6 addresses of the mail servers that will be permitted to send emails from your emails. As an added option you can even restrict the email messages to be sent from your domain only if it has our MX records, i.e. when our servers manage the e-mail addresses for it, not a third-party provider. This feature gives you the top standard of security, but it's not applicable if only your web site is on our servers while the e-mail addresses for the domain are handled elsewhere. In either case, our SPF protection service will keep your email addresses risk-free from being used for spam and/or scam purposes.
SPF Protection in Semi-dedicated Hosting
The SPF protection attribute is featured with all of the Linux semi-dedicated hosting packages, so if you host your domains in an account on our cloud web hosting platform, you can activate the service effortlessly for all your domain names. The Hepsia Control Panel, which comes with the semi-dedicated accounts, has a very intuitive interface, so you don't need to be proficient in the use of computers to secure your e-mail addresses. You will simply have to type the hostname and the IP of each mail server that you'd like to be allowed to send out emails from your addresses and right after that the updated record will be activated for the domain name that you've selected. As a further option, we will also allow you to restrict the outgoing email messages and secure your mailboxes even further by allowing e-mail messages to be sent only when the domain name involved has our MX records i.e. the emails for the domain need to be taken care of on our end and not by some other company. By doing this you'll have even superior control and there won't be any chances for anyone to forge your email addresses for harmful uses.
