Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called email spoofing where an e-mail message is sent from one e-mail, but to look as being sent from another one, ordinarily with the idea to scam the recipient in some way. When SPF protection is activated for a domain, an exclusive record is generated for it in the Domain Name System and all of the DNS servers worldwide receive it. The record contains all mail servers that are allowed to send authentic messages from an e-mail address under the domain. When an email 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 targeted receiver. In case, however, the sending server is not present in the SPF record for the given domain, the message won't be submitted and it will be removed. When you use this service, it'll prevent third parties from sending spam which look as if they have been sent by you.
SPF Protection in Web Hosting
You'll be able to enable the SPF protection option for your domain names with just a couple of clicks from the Hepsia Control Panel, which comes with all our Linux web hosting service. This carried out through the section with the same name and you are able to set up the protection for any domain hosted on our cutting-edge cloud hosting platform. Using a very convenient interface, all you'll need to enter is the hostname of the mail server that will be approved to send messages from your emails and its IPv4 or IPv6 address. Last, but not least, you're able to add several servers as well, when needed. In case your e-mail addresses are taken care of by us, you can also use a more risk-free option by setting a limit that e-mail messages can be sent only if your domains have our MX records. This alternative can't be applied if your web site is here, but the e-mail addresses are with a third-party service provider. Either way, the SPF protection option will vastly improve your online security and stop other people from spoofing your email addresses.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account with us, you are able to protect your email addresses by enabling the SPF protection service for every domain in your account with only a couple of clicks. This is done in the Emails section of our Hepsia Control Panel which is included with the semi-dedicated accounts and even in case you have no previous experience with such matters, you will not have any kind of trouble to enable the protection. Everything that you will have to do will be to select a domain name from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your emails will be sent around the world only if they're sent from that particular server. In case your emails are handled by our company and not by a third-party supplier, you'll also be able to use an option for email messages to be sent only if the domain name has our MX records and the latter is the most secure option. Should you have any questions related to thisfunction, you will be able to get in touch with our tech support crew 24/7.
