Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called email spoofing where an email message is sent from one email, but to seem as being sent from another one, often with the objective to fraud the recipient in some way. If SPF protection is enabled for a domain, a special record is generated for it in the Domain Name System and all of the DNS servers around the world have it. The record contains all of the email servers that are permitted to send authentic messages from an email address within the domain. When a message 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. When, however, the sending server doesn't exist in the SPF record for the specified domain, the email message will not be sent and it will be removed. If you employ this solution, it'll prevent third parties from sending spam which seem to have been sent by you.
SPF Protection in Cloud Hosting
SPF protection can be enabled for each domain hosted in a cloud hosting account on our cloud platform with only a few clicks. The option is available in the Emails section of our state-of-the-art Hepsia Control Panel and all it takes to enable it is to pick one of your domains from the drop-down list and type in the hostnames together with the IPv4 or IPv6 addresses of the mail servers that will be authorized to send email messages from your emails. As an added option you can even restrict the messages to be sent from your domain only when it has our MX records, in other words if our servers handle the e-mail addresses for it, not a third-party supplier. This option will provide you with the highest level of safety, but it is not applicable if only your site is on our servers while the email addresses for the domain name are managed elsewhere. Regardless, the SPF protection service will keep your emails safe from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account with us, you can protect your email addresses by enabling the SPF security service for any domain name in your account with only a few mouse-clicks. You can do this through 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 kinds of issues, you won't have any kind of trouble to activate the security. The only things that you'll need to do will be to choose a domain name from a drop-down list then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be sent globally only if they were sent from that specific server. If your email addresses are handled by us and not by a third-party provider, you will also be able to benefit from an option for e-mail messages to be mailed only if the domain name has our MX records and the aforementioned would be the most secure option. If you have any kind of questions about thisfunction, you'll be able to contact our tech support crew 24/7.
