Sender Policy Framework, or SPF, is a validation system, that is intended to stop the so-called email spoofing where an email message can be sent from one address, but to appear as being sent from another, generally with the idea to fraud the recipient for some reason. When SPF protection is enabled for a domain, a special record is made for it in the Domain Name System and all of the DNS servers globally have it. The record features all email servers that are permitted to send legitimate messages from an email address within the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and in case the sending server is permitted, the message is sent to the targeted receiver. In case, however, the sending server is not contained in the SPF record for the specified domain, the message will not be submitted and it'll be discarded. If you employ this service, it'll prevent third parties from sending spam messages which appear to have been sent from you.

SPF Protection in Shared Hosting

When you host your domains in a shared hosting account on our end and we handle the email addresses for them, you'll be able to enable SPF protection for them with several clicks in your Hepsia Control Panel. The service is available in a separate section where you can view which domain names are currently secured. For the ones which aren't, you'll be able to enable the SPF protection option and set up a number of things in the process - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and even to set a rule that email messages can be sent only when your domains have our MX records. The last choice is the most secure one, and you can use it in the event that we handle the email addresses for your domain names and you're not using another e-mail service provider. The new records will propagate within a day and nobody will be able to forge the FROM field in a message with your addresses.

SPF Protection in Semi-dedicated Servers

The Hepsia hosting Control Panel, that is included with our semi-dedicated service, provides you with a very intuitive interface to activate the SPF security service for any domain that you host in your new account. A few clicks in the Emails section of Hepsia will be enough for that then you'll only have to type in the hostname and the IP address of the mail server that will be permitted to send messages from your e-mail addresses. When the e-mail messages are taken care of on our end and not by a different provider, you will be able to raise the security level even more and activate an option for all of the outgoing email messages to be sent only if your domain names include our MX records. This option will provide you with better control and it'll eliminate any possibility of anyone faking your e-mails with the objective of spamming or scamming people. It is not applicable in case just your site is hosted on our innovative cloud hosting platform, while your emails are handled by some other service provider. If you aren't sure what features to pick, our tech support staff will assist you 24/7.
