Sender Policy Framework, or SPF, is a verification system, which is intended to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email address, but to seem as being sent from another, ordinarily with the idea to fraud the recipient in some way. If SPF protection is enabled for a domain name, a unique record is created for it in the Domain Name System and all the DNS servers globally get it. The record features all email servers that are permitted to send valid messages from an email address under the domain. When an email is sent, the very first DNS server it encounters verifies the SPF record and if its sending server is authorized, the message is forwarded to the targeted receiver. In case, however, the sending server is not contained in the SPF record for the given domain, the message won't be forwarded and it will be discarded. If you use this service, it will stop third parties from sending spam messages that look as if they have been sent by you.
SPF Protection in Shared Website Hosting
SPF protection can be enabled for any domain name hosted in a shared website hosting account on our cloud platform with no more than a few mouse-clicks. The option can be found in the Emails section of our modern Hepsia Control Panel and all it takes to activate it is to choose one of your domain names from the drop-down list and to enter the hostnames along with the IPv4 or IPv6 addresses of the mail servers that will be permitted to send email messages from your email addresses. As an additional option you can even restrict the messages to be sent from your domain only when it includes our MX records, i.e. when our servers handle the emails for it, not a third-party supplier. This feature gives you the best degree of security, but it is not applicable when only your site is on our servers while the e-mail addresses for the domain name are handled in another place. Either way, the SPF protection service will keep your emails protected from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Servers
The Hepsia website hosting Control Panel, that is included with all of our Linux semi-dedicated plans, will provide you with an exceptionally easy-to-use interface to enable the SPF security service for every domain that you host in your new account. Several clicks in the Emails section of Hepsia are enough for that then you'll only have to type in the hostname and the IP address of the mail server which will be permitted to send messages from your email addresses. If the e-mails are taken care of by us and not by another supplier, you will be able to boost the protection level even further and activate an option for all of the outgoing email messages to be sent only if your domains include our MX records. This option gives you better control and it'll eliminate any chance of anyone faking your e-mails with the purpose of spamming and scamming people. It is not applicable in case just your website is on our outstanding cloud hosting platform, while your e-mails are managed by another provider. If you aren't sure what features to select, our tech support crew will assist you 24/7.
