Sender Policy Framework, or SPF, is a validation system, that is employed to stop the so-called email spoofing where an e-mail message is sent from one address, but to seem as being sent from another, generally with the objective to fraud the recipient someway. When SPF protection is activated for a domain, a special record is made for it in the Domain Name System and all of the DNS servers worldwide get it. The record contains all email servers that are permitted to send authentic messages from an address within the domain. When an email is sent, the first DNS server it goes to checks the SPF record and in case its sending server is permitted, the message is forwarded to the target receiver. In case, however, the sending server is not contained in the SPF record for the given domain, the email message won't be sent and it will be removed. When you employ this solution, it'll prevent third parties from sending spam e-mails which look as if they have been sent from you.
SPF Protection in Hosting
If you host your domain names in a hosting account with us and we manage the emails for them, you are able to enable SPF protection for them with a few clicks inside your Hepsia Control Panel. This service can be found in a section of its own where you are able to view which domain names are already secured. For those which aren't, you will be able to activate the SPF protection solution and set up a variety of things at the same time - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that email messages can be sent only if your domains use our MX records. The aforementioned solution is the most secure one, and you can use it in the event that we take care of the e-mail addresses for your domains and do not use a different email supplier. The newly created records will propagate within one day and nobody will be able to forge the FROM field in an email by using your e-mail addresses.
SPF Protection in Semi-dedicated Servers
The Hepsia hosting Control Panel, which comes with all our Linux semi-dedicated servers, provides you with a really user-friendly interface to activate the SPF protection service for every domain name that you host in your new account. Just a few clicks in the Emails section of Hepsia will be enough for that and you will only have to type in the hostname and the IP address of the mail server which will be permitted to send out messages from your email addresses. When the e-mails are managed on our end and not by a different provider, you're able to raise the protection level even more and take advantage of an option for all of the outgoing e-mails to be sent only if your domains feature our MX records. This option provides you with more control and it will eliminate any chance of anybody forging your emails with the intention of spamming and scamming people. It's not applicable if only your web site is hosted on our modern cloud hosting platform, while your emails are managed by another provider. If you are not sure what options to pick, our technical support staff will help you 24/7.
