Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called email spoofing where an email message is sent from one address, but to seem as being sent from another one, typically with the objective to fraud the recipient for some reason. If SPF protection is enabled for a domain, a specific record is created for it in the Domain Name System and all the DNS servers worldwide get it. The record includes all the e-mail servers that are allowed to send legitimate messages from an address part of the domain. When an email is sent, the very first DNS server it encounters verifies the SPF record and in case its sending server is authorized, the message is forwarded to the target receiver. In case, however, the sending server is not included in the SPF record for the given domain, the email message won't be sent and it will be removed. When you employ this service, it will stop third parties from sending spam emails that seem to have been sent by you.
SPF Protection in Cloud Website Hosting
You are able to enable the SPF protection service for your domains with only a few clicks inside the Hepsia Control Panel, which is included in all of our cloud website hosting. This is done through the section with an identical name and you'll be able to allow the protection for each and every domain name on our cutting-edge cloud hosting platform. Using a very user-friendly interface, all you'll have to enter is the hostname of the mail server which will be authorized to send messages from your email addresses and its IPv4 or IPv6 address. Of course, you are able to add several servers too, when needed. When your e-mails are handled by us, you may also use an even more secure option by setting a restriction that messages can be sent only when your domains have our MX records. This alternative cannot be applied in case your website is here, while your e-mails are with a third-party service provider. In either case, the SPF protection solution will vastly improve your web security and stop other people from counterfeiting your e-mail addresses.

This is done in the Emails section of the Hepsia Control Panel that comes with the semi-dedicated accounts and even if you lack previous experience with such matters, you will not have any kind of trouble to enable the security. Everything that you'll have to do will be to choose a domain from a drop-down menu and then type in the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your e-mail addresses will be delivered globally only if they are sent from that particular server. In case your e-mail addresses are managed 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 has our MX records and the aforementioned is the safest option.
