Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called e-mail spoofing where an email message can be sent from one e-mail address, but to appear as being sent from another, generally with the idea to scam the recipient in some way. If SPF protection is activated for a domain name, a special record is generated for it in the Domain Name System and all the DNS servers globally get it. The record contains all the mail servers that are permitted to send valid messages from an e-mail address within the domain. When a message is sent, the first DNS server it encounters verifies the SPF record and in case its sending server is authorized, the message is forwarded to the target receiver. When, however, the sending server is not included in the SPF record for the given domain, the message will not be sent and it will be discarded. If you employ this service, it will prevent third parties from sending spam messages which appear to have been sent from you.

SPF Protection in Shared Website Hosting

When you host your domain names in a shared website hosting account on our end and we manage the e-mail addresses for them, you are able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service can be found in a separate section where you are able to see which domain names are already secured. For those that aren't, you can activate the SPF protection solution and set up a variety of things during the process - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and to create a rule that emails can be sent only if your domain names use our MX records. The last option is the most secure one, but you can use it in the event that we manage the emails for your domain names and do not use a different e-mail service provider. The new records will propagate within 24 hours and nobody will be able to forge the FROM field in an e-mail with your email addresses.

SPF Protection in Semi-dedicated Hosting

The SPF protection attribute is provided with all the Linux semi-dedicated hosting, so if you host your domain names in an account on our cloud website hosting platform, you'll be able to use this service effortlessly for all of your domain names. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, has a really easy to work with interface, so you won't have to be tech-savvy in order to protected your e-mails. You will only have to type the hostname and the IP address of each mail server that you'd like to be authorized to send emails from your addresses and shortly after that the updated record will be activated for the domain that you have picked. As an extra option, we will also allow you to control your outgoing e-mail messages and secure your mailboxes further by allowing messages to be sent only when the domain name involved features our MX records i.e. the email messages for the domain name should be handled on our end and not by another provider. By doing so you'll get even superior control and there will not be any chances for any person to forge your e-mail addresses for malicious uses.
