Sender Policy Framework, or SPF, is a validation system, which is designed to stop the so-called e-mail spoofing where an email message is sent from one email, but to seem as being sent from another, usually with the idea to fraud the recipient someway. If SPF protection is activated for a domain, an exclusive record is created for it in the Domain Name System and all of the DNS servers globally have it. The record features all the mail servers that are allowed to send authentic messages from an email address part of the domain. When a message is sent, the first DNS server it encounters checks the SPF record and when the sending server is permitted, the message is forwarded to the targeted receiver. When, however, the sending server is not present in the SPF record for the particular domain, the e-mail message won't be sent and it'll be discarded. In case you employ this solution, it'll stop third parties from sending spam messages which seem to have been sent from you.
SPF Protection in Shared Web Hosting
If you host your domain names in a shared web hosting account on our end and we manage the email addresses for them, you are able to enable SPF protection for them with a couple of clicks in your Hepsia Control Panel. The service can be found in its own section where you can see which domains are currently secured. For those that are not, you'll be able to activate the SPF protection option and configure a lot of things in the process - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of these servers, and even to create a rule that emails can be sent only if your domain names use our MX records. The last option is the most secure one, but you can use it in the event that we take care of the emails for your domains and do not use some other email supplier. The newly generated records will be activated within a day and nobody will be able to fake the FROM field in an email with your e-mail addresses.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account with us, you will be able to secure your emails by enabling the SPF security service for every domain name in the account with only a couple of clicks. This is done through the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even if you have no previous practical experience with such things, you won't have any kind of trouble to activate the protection. The only things that you will need to do will be to choose a domain from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your e-mail addresses will be delivered around the world only if they are sent from that server. If your e-mail addresses are managed by our company and not by a third-party provider, you can also benefit from an option for email messages to be sent only if the domain name features our MX records and the aforementioned would be the most secure option. If you have any kind of questions about thisfeature, you will be able to get in touch with our support crew 24/7.
