Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called e-mail spoofing where an email message can be sent from one e-mail, but to appear as being sent from another one, generally with the objective to fraud the recipient for some reason. When SPF protection is activated for a domain name, an exclusive record is generated for it in the Domain Name System and all of the DNS servers around the world get it. The record features all of the e-mail servers that are permitted to send authentic messages from an address under the domain. When an email is sent, the first DNS server it goes to checks the SPF record and in case the sending server is authorized, the message is forwarded to the target destination. In case, however, the sending server is not contained in the SPF record for the particular domain, the message will not be sent and it will be discarded. Whenever you employ this solution, it'll stop third parties from sending spam messages that appear to have been sent by you.
SPF Protection in Cloud Hosting
If you host your domain names in a cloud hosting account on our end and we manage the e-mail addresses for them, you are able to activate SPF protection for them with a couple of clicks in your Hepsia Control Panel. This service is available in its own section where you will be able to see which domains are currently protected. For those that are not, you can activate the SPF protection service and set up a number of things during this process - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, as well as to create a rule that messages can be sent only if your domains use our MX records. The last option is the most secure one, but you can use it if we handle the e-mails for your domain names and you're not using a different e-mail supplier. The newly generated records will be activated within one day and nobody will be able to forge the FROM field in an email by using your email addresses.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from our company, you are able to secure your emails by activating the SPF security service for any domain in your account with only a few 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 lack previous practical experience with these kinds of things, you will not have any kind of difficulties to activate the security. Everything that you will have to do will be to find a domain from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your email addresses will be mailed globally only if they're sent from that particular server. When your e-mail addresses are taken care of by us and not by a third-party provider, you can also use an option for e-mail messages to be sent only if the domain includes our MX records and the latter is the most secure option. If you have any kind of questions regarding thisfeature, you will be able to contact our technical support team 24/7.
