Sender Policy Framework, or SPF, is a verification system, which is intended to prevent the so-called email spoofing where an email message can be sent from one email address, but to appear as being sent from another, frequently with the idea to fraud the recipient for some reason. If SPF protection is enabled for a domain, a unique record is made for it in the Domain Name System and all DNS servers around the world get it. The record features all mail servers that are allowed to send legitimate messages from an address within the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and if the sending server is permitted, the message is forwarded to the target destination. In case, 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 discarded. If you employ this service, it will stop third parties from sending spam e-mails that appear to have been sent from you.
SPF Protection in Cloud Hosting
When you host your domain names in a cloud hosting account with us and we handle the email addresses for them, you'll be able to enable SPF protection for all of them with a few clicks inside your Hepsia Control Panel. The service is available in a section of its own where you are able to view which domain names are already secured. For those that are not, you'll be able to enable the SPF protection solution and configure numerous things at the same time - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, and even to create a rule that messages can be sent only when your domains use our MX records. The aforementioned option is the most secure one, but you can use it in the event that we take care of the e-mails for your domain names and do not use some other e-mail service provider. The new records will propagate within a day and nobody will be able to fake the FROM field in a message by using your email addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account with us, you will be able to protect your email addresses by enabling the SPF security service for any domain hosted in the account with only a few mouse-clicks. This is done in the Emails section of the Hepsia Control Panel which comes with the semi-dedicated accounts and even if you lack previous experience with these kinds of things, you won't have any kind of troubles to enable the security. The only things that you'll have to do will be to pick a domain name from a drop-down list then type in the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your emails will be delivered worldwide only if they are sent from that specific server. If your email addresses are handled by us and not by a third-party supplier, you'll also be able to activate an option for e-mail messages to be sent only if the domain features our MX records and the latter would be the most secure option. In case you have any kind of questions about thisfeature, you'll be able to contact our support crew 24/7.
