Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called e-mail spoofing where an e-mail message is sent from one address, but to look as being sent from another, typically with the idea to scam the recipient in some way. If SPF protection is enabled for a domain, a specific record is made for it in the Domain Name System and all of the DNS servers around the world get it. The record contains all of the mail servers that are permitted to send valid messages from an e-mail address under the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and in case the sending server is permitted, the message is sent to the target destination. When, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message will not be sent and it'll be removed. Whenever you employ this service, it'll prevent third parties from sending spam e-mails that look as if they have been sent by you.
SPF Protection in Cloud Hosting
SPF protection can be activated for every domain hosted in a cloud hosting account on our cloud platform with only a few mouse-clicks. The feature is available in the Emails section of our leading-edge Hepsia Control Panel and all you need to enable it is to pick one of your domain names from the drop-down menu and then type in the hostnames plus the IPv4 or IPv6 addresses of the mail servers which will be approved to send email messages from your email addresses. As an additional option you may also restrict the e-mails to be sent from your domain only if it includes our MX records, in other words if our servers manage the e-mail addresses for it, not a third-party provider. This option provides you with the top level of protection, but it is not applicable if only your web site is on our servers while your emails for the domain are handled in another place. Either way, the SPF protection service will keep your email addresses safe from being used for spam and/or scam purposes.
SPF Protection in Semi-dedicated Hosting
The Hepsia web hosting Control Panel, which comes with all our Linux semi-dedicated hosting, offers you a really intuitive interface to activate the SPF protection service for every domain name that you host within your new account. Just a few clicks in the Emails section of Hepsia are enough for that and you will only have to enter the hostname and the IP address of the mail server which will be allowed to send out messages from your email addresses. If the e-mail messages are taken care of by us and not by some other supplier, you'll be able to increase the protection level even more and take advantage of an option for your outgoing e-mails to be sent only if your domains use our MX records. This option will provide you with increased control and it'll eliminate any possibility of anyone faking your emails with the intention of spamming and scamming people. It's not applicable if only your site is on our innovative cloud hosting platform, while your e-mail addresses are managed by another service provider. If you are not sure what features to pick, our technical support crew will help you 24/7.
