Sender Policy Framework, or SPF, is a validation system, which is used to prevent the so-called email spoofing where an e-mail message can be sent from one address, but to seem as being sent from another, often with the purpose to fraud the recipient in some way. If SPF protection is enabled for a domain name, a unique record is made for it in the Domain Name System and all of the DNS servers globally have it. The record includes all the email servers that are allowed to send valid messages from an address within the domain. When an e-mail is sent, the first DNS server it encounters verifies the SPF record and if the sending server is authorized, the message is sent to the targeted destination. If, however, the sending server is not present in the SPF record for the given domain, the e-mail message won't be forwarded and it will be removed. In case you use this solution, it will prevent third parties from sending spam emails which look as if they have been sent from you.
SPF Protection in Shared Hosting
SPF protection can be enabled for every domain hosted in a shared hosting account on our cloud platform with just a few clicks. The option is available in the Emails section of our outstanding Hepsia Control Panel and all it takes to use it is to pick one of your domains from the drop-down list and to enter the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers which will be authorized to send messages from your email addresses. As an added option you may also restrict the messages to be sent from your domain name only when it includes our MX records, i.e. if our servers manage the emails for it, not a third-party provider. This solution gives you the top standard of security, but it's not applicable in case only your site is on our servers while the email addresses for the domain are handled in a different place. Regardless, our SPF protection service will keep your emails secure from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from our company, you can secure your email addresses by enabling the SPF protection service for any domain hosted in your account with only a few clicks. This is done from the Emails section of our Hepsia Control Panel which is provided with the semi-dedicated accounts and even in case you have no previous practical experience with these things, you will not have any trouble to activate the protection. Everything that you'll need to do will be to pick a domain from a drop-down list then type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your email addresses will be delivered globally only if they were sent from that server. If your e-mail addresses are managed by us and not by a third-party supplier, you will also be able to use an option for emails to be mailed only when the domain includes our MX records and this would be the safest option. When you have any kind of questions regarding thisfunction, you'll be able to get in touch with our technical support team 24/7.
