Sender Policy Framework, or SPF, is a validation system, which is employed 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 a different one, frequently with the idea to scam the recipient for some reason. If SPF protection is activated for a domain, a special record is generated for it in the Domain Name System and all of the DNS servers worldwide have it. The record features all email servers that are allowed to send legitimate messages from an email address part of the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and if the sending server is authorized, the message is sent to the targeted destination. When, however, the sending server is not present in the SPF record for the given domain, the message won't be forwarded and it will be removed. When you employ this solution, it will prevent third parties from sending spam messages which look as if they have been sent from you.
SPF Protection in Website Hosting
If you host your domains in a website hosting account on our end and we handle the email addresses for them, you will be able to enable SPF protection for them with a couple of clicks in your Hepsia Control Panel. The service is available in a section of its own where you will be able to see which domain names are already secured. For those that aren't, you'll be able to activate the SPF protection service and set up a number of things in the process - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, as well as to create a rule that messages can be sent only if your domain names use our MX records. The last choice is the most secure one, and you can use it in the event that we handle the emails for your domain names and you are not using a different e-mail provider. The new records will propagate within a day and nobody will be able to forge the FROM field in an e-mail using your e-mail addresses.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from our company, you will be able to protect your email addresses by enabling the SPF security service for every domain in the account with only a couple of clicks. You can do this in the Emails section of our Hepsia Control Panel which is provided with the semi-dedicated accounts and even if you have no previous practical experience with such things, you will not have any kind of problems to enable the security. Everything that you will have to do will be to choose a domain name from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your emails will be sent globally only if they are sent from that particular server. If your emails are managed by us and not by a third-party provider, you can also activate an option for emails to be sent only if the domain includes our MX records and the latter would be the safest option. In case you have any kind of questions regarding thisfeature, you'll be able to get in touch with our support crew 24/7.
