SPF, which means Sender Policy Framework, is an e-mail safety system, which is is intended to verify if an e-mail message is sent by a certified server. Employing SPF protection for a given domain will prevent the counterfeiting of email addresses generated with the domain. In simple words: enabling this function for a domain makes a specific record in the Domain Name System (DNS) which contains the IP addresses of the servers which are allowed to send emails from mailboxes under the domain. The moment this record propagates worldwide, it will exist on all the DNS servers that direct the Internet traffic. When a new email message is sent, the first DNS server it uses tests whether it originates from an approved server. If it does, it is forwarded to the destination address, but when it does not come from a server part of the SPF record for the particular domain, it's rejected. In this way nobody can mask an email address to make it look as if you're e-mailing spam. This technique is also identified as email spoofing.
SPF Protection in Shared Web Hosting
The SPF protection option is available as standard with each shared web hosting package that we supply and you'll be able to use it with ease to protect the e-mail addresses for any domain name hosted in your account. The service is handled from the Emails section of our cutting-edge, albeit intuitive Hepsia Control Panel. What is needed to enable the protection is to type in the IP of the mail server and its hostname - mail.server.com, for example. When the protection is active, only this server will be able to send e-mail messages from email addresses generated under the domain name that you've selected. Your e-mail addresses can be taken care of by some other company, but when we manage them together with your website, you can also enable the option for your e-mail messages to be sent only when the domain has our MX records. This selection will provide you with even better security as just our server will be authorized to send out e-mail messages from your mailboxes and you'll have superior control. When you have any kind of questions or in case you have any kind of problems with this particular service, you can contact our technical support team at any time and they'll give you a hand immediately.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from us, you can secure your emails by activating the SPF security service for any domain name hosted in your account with only a few clicks. This is done from the Emails section of the Hepsia Control Panel which is provided with the semi-dedicated accounts and even when you have no previous experience with such matters, you won't have any kind of difficulties to enable the protection. The only things that you will need to do is to select a domain from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your emails will be delivered globally only if they are sent from that specific server. In case your emails are managed by us and not by some third-party provider, you'll also be able to take advantage of an option for emails to be sent only if the domain includes our MX records and the latter is the most secure option. When you have any questions regarding thisfunction, you can contact our support crew 24/7.
