Sender Policy Framework, or SPF, is a validation system, which is designed to prevent the so-called e-mail spoofing where an email message is sent from one address, but to seem as being sent from another one, usually with the objective to scam the recipient someway. When SPF protection is activated for a domain name, a unique record is made for it in the Domain Name System and all of the DNS servers around the world have it. The record features all of the mail servers that are permitted to send legitimate messages from an address part of the domain. When a message is sent, the first DNS server it encounters checks the SPF record and if the sending server is authorized, the message is sent to the targeted destination. When, however, the sending server is not included in the SPF record for the given domain, the message will not be submitted and it will be discarded. If you employ this service, it will prevent third parties from sending spam messages that seem to have been sent by you.
SPF Protection in Web Hosting
SPF protection can be activated for every domain name hosted in a web hosting account on our cloud hosting platform with no more than a few mouse-clicks. The feature can be found in the Emails section of our revolutionary Hepsia Control Panel and all it takes to use it is to pick one of your domains from a drop-down list and to type in the hostnames together with the IPv4 or IPv6 addresses of the mail servers which will be authorized to send messages from your email addresses. As an added option you may also restrict the e-mails 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 solution will give you the top level of safety, but it is not applicable in case only your web site is on our servers while your email addresses for the domain name are managed in another place. In either case, the SPF protection service will keep your emails risk-free from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Hosting
The SPF protection feature is featured with all Linux semi-dedicated packages, so when you host your domain names in an account on our cloud hosting platform, you'll be able to activate this service with ease for all of your domains. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, has a quite easy to work with interface, so you will not have to be proficient in the use of computers in order to secure your e-mails. You'll simply have to type the hostname and the IP address of each mail server that you'd like to be allowed to send out emails from your addresses and shortly after that the new record will be activated for the domain that you have picked. As a further option, we will also allow you to restrict the outgoing e-mail messages and protect your mailboxes even better by allowing email messages to be sent only when the domain involved has our MX records i.e. the e-mail messages for the domain name need to be taken care of by us and not by a different provider. Doing so you'll enjoy even better control and there will not be any chance for any person to forge your e-mails for malicious activities.
