Sender Policy Framework, or SPF, is a validation system, which is used to stop the so-called email spoofing where an email message can be sent from one email address, but to appear as being sent from a different one, frequently with the objective to scam the recipient someway. If SPF protection is activated for a domain name, a unique record is created for it in the Domain Name System and all of the DNS servers globally have it. The record includes all of the email servers that are allowed to send legitimate messages from an e-mail address part of the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and in case its sending server is permitted, the message is forwarded to the target receiver. When, however, the sending server is not contained in the SPF record for the particular domain, the e-mail message won't be forwarded and it will be discarded. In case you use this service, it'll stop third parties from sending spam messages which look as if they have been sent from you.
SPF Protection in Shared Website Hosting
When you host your domain names in a shared website hosting account with us and we handle the e-mails for them, you are able to activate SPF protection for any of them with several clicks inside your Hepsia Control Panel. This service is accessible in a section of its own where you will be able to see which domains are already secured. For those that are not, you will be able to enable the SPF protection option and set up numerous 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 these servers, and to set a rule that email messages can be sent only when your domains use our MX records. The aforementioned option is the most secure one, and it can be used in the event that we handle the emails for your domain names and do not use a different email supplier. The newly generated records will be activated within one day and nobody will be able to fake the FROM field in an e-mail with your addresses.
SPF Protection in Semi-dedicated Servers
The Hepsia web hosting Control Panel, which comes with our Linux semi-dedicated hosting plans, will provide you with an exceptionally easy-to-use interface to enable the SPF protection service for every domain that you host within your new account. A few clicks in the Emails section of Hepsia are enough for that and you'll only have to enter the hostname and the IP address of the mail server which will be permitted to send messages from your emails. When the emails are managed on our end and not by another provider, you are able to boost the security level even more and enable an option for all the outgoing emails to be sent only if your domain names use our MX records. This option will provide you with better control and it will eliminate any possibility of someone faking your e-mails with the objective of spamming and scamming people. It's not applicable in case only your web site is on our hi-tech cloud hosting platform, while your e-mails are managed by another service provider. If you are not sure what options to choose, our technical support team will help you 24/7.
