SPF, which stands for Sender Policy Framework, is an email security system, that is designed to confirm whether an e-mail message was sent by an authorized server. Using SPF protection for a domain name will stop the counterfeiting of email addresses made with the domain. In simple words: enabling this feature for a domain generates a particular record in the Domain Name System (DNS) which contains the IP of the servers which are permitted to send email messages from mailboxes under the domain. The moment this record propagates worldwide, it will exist on all the DNS servers that direct the Internet traffic. Every time some e-mail message is sent, the initial DNS server it goes through checks whether it originates from an approved server. When it does, it's sent to the destination address, however when it does not come from a server listed in the SPF record for the particular domain, it's rejected. Thus nobody will be able to mask an e-mail address then make it appear as if you are sending spam. This approach is also identified as email spoofing.
SPF Protection in Cloud Web Hosting
You are able to activate the SPF protection option for your domains with just a couple of clicks in the Hepsia Control Panel, which is included in all our Linux cloud web hosting packages. This is done via the section with the same name and you are able to allow the protection for each and every domain on our outstanding cloud hosting platform. Using a really time and effort saving interface, all you'll have to enter is the hostname of the mail server that will be permitted to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, you are able to add several servers as well, when needed. When your email addresses are taken care of by us, you may also take advantage of an even more secure option by putting a restriction that messages can be sent only if your domains feature our MX records. This option can't be applied when your web site is here, and your email addresses are with a third-party service provider. In either case, the SPF protection option can strongly increase your web security and prevent other people from counterfeiting your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
The SPF protection feature is provided with all Linux semi-dedicated packages, so in case you host your domains in an account on our cloud website hosting platform, you are able to use this service with ease for all your domain names. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, features a very easy to use interface, therefore you do not have to be proficient in the use of computers in order to protected your e-mails. You'll simply have to type the hostname and the IP of each mail server that you'd like to be authorized to send out e-mails from your addresses and shortly after that the updated record will be activated for the domain name that you've chosen. As an additional option, we will also allow you to restrict the outgoing email messages and secure your mailboxes further by permitting e-mail messages to be sent only when the domain involved includes our MX records i.e. the emails for the domain name should be managed by us and not by some other company. By doing this you will get even better control and there won't be a chance for any person to counterfeit your e-mails for malicious uses.
