Sender Policy Framework, or SPF, is a validation system, which is designed to stop the so-called email spoofing where an e-mail message is sent from one e-mail, but to look as being sent from another, frequently with the objective to fraud the recipient someway. When SPF protection is enabled for a domain, a unique record is made for it in the Domain Name System and all of the DNS servers globally get it. The record features all the mail servers that are permitted to send valid messages from an e-mail address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and when the sending server is authorized, the message is forwarded to the targeted receiver. When, however, the sending server is not contained in the SPF record for the given domain, the message won't be forwarded and it'll be discarded. In case you use this solution, it'll prevent third parties from sending spam messages which appear to have been sent by you.
SPF Protection in Cloud Hosting
When you host your domain names in a cloud hosting account with us and we manage the e-mails for them, you will be able to enable SPF protection for any of them with a few clicks in your Hepsia Control Panel. The service is accessible in its own section where you're able to see which domains are currently protected. For the ones that are not, you can enable the SPF protection solution and set up various 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, as well as to create a rule that emails can be sent only when your domain names use our MX records. The last solution is the most secure one, and you can use it when we manage the email addresses for your domains and you're not using another email supplier. The new records will be activated within 24 hours and nobody will be able to fake the FROM field in an email by using your email addresses.
SPF Protection in Semi-dedicated Servers
The Hepsia web hosting Control Panel, which comes with all our Linux semi-dedicated servers, offers you an extremely intuitive interface to activate the SPF security service for each domain that you host within your new account. A couple of clicks in the Emails section of Hepsia are enough for that and you'll only have to type in the hostname and the IP address of the mail server which will be permitted to send messages from your e-mail addresses. When the e-mail messages are managed by us and not by another supplier, you can increase the protection level even more and activate an option for the outgoing e-mails to be sent only if your domains include our MX records. This option will provide you with increased control and it'll eliminate any possibility of someone faking your e-mail addresses with the objective of spamming or scamming people. It is not applicable if only your site is on our outstanding cloud web hosting platform, while your email addresses are managed by a different provider. If you are not sure what options to pick, our tech support crew will assist you 24/7.
