Sender Policy Framework, or SPF, is a validation system, that is intended to prevent the so-called email spoofing where an email message is sent from one e-mail, but to seem as being sent from another one, generally with the idea to fraud the recipient in some way. When SPF protection is enabled for a domain name, a unique record is made for it in the Domain Name System and all of the DNS servers globally get it. The record contains all of the email servers that are permitted to send valid messages from an e-mail address part of the domain. When an email is sent, the first DNS server it goes to checks the SPF record and in case its sending server is authorized, the message is sent to the targeted destination. If, however, the sending server doesn't exist in the SPF record for the given domain, the message will not be forwarded and it will be removed. Whenever you employ this solution, it will prevent third parties from sending spam which seem to have been sent by you.
SPF Protection in Shared Hosting
The SPF protection function is accessible by default with each and every shared hosting package that we supply and you can use it without difficulty to protect the e-mails for any domain name hosted in your account. The service is controlled through the Emails section of our advanced, albeit intuitive Hepsia Control Panel. All you need to activate the protection is to type the IP of the e-mail server plus its hostname -, for instance. As soon as the protection is activated, only this server will be able to send out emails from email addresses created under the domain that you've selected. Your e-mail addresses can be managed by a different provider, but in case that we handle them in addition to your website, you can activate an option for your messages to be sent only when the domain features our MX records. This selection will provide you with greater security as solely our server will be permitted to send out email messages from your mailboxes and you will have improved control. If you have any questions or in case you experience any kind of issues with this service, you can contact our technical support crew anytime and they'll help you in a timely manner.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account with us, you will be able to secure your emails by activating the SPF security service for every domain in the account with just a couple of clicks. This is done in the Emails section of the Hepsia Control Panel that comes with the semi-dedicated accounts and even in case you have no previous practical experience with such issues, you will not have any kind of difficulties to enable the security. The only things that you'll need to do will be to find a domain name from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your emails will be delivered globally only if they are sent from that server. If your email addresses are managed by us and not by a third-party provider, you will also be able to activate an option for e-mail messages to be mailed only when the domain features our MX records and the latter is the safest option. If you have any kind of questions related to thisfunction, you'll be able to contact our tech support team 24/7.
