Sender Policy Framework, or SPF, is a verification system, that is intended to prevent the so-called e-mail spoofing where an email message is sent from one address, but to look as being sent from another, typically with the idea to scam the recipient someway. If SPF protection is activated for a domain, an exclusive record is generated for it in the Domain Name System and all DNS servers worldwide receive it. The record features all of the email servers that are permitted to send authentic messages from an e-mail address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and when the sending server is permitted, the message is sent to the targeted destination. When, however, the sending server doesn't exist in the SPF record for the specified domain, the message won't be sent and it will be removed. In case you employ this solution, it'll prevent third parties from sending spam messages that appear to have been sent from you.
SPF Protection in Shared Web Hosting
When you host your domain names in a shared web hosting account with us and we handle the e-mail addresses for them, you are able to enable SPF protection for them with a couple of clicks in your Hepsia Control Panel. This service is available in a separate section where you'll be able to view which domains are currently protected. For those which aren't, you can enable the SPF protection service and manage a number of things at the same time - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, as well as to set a rule that emails can be sent only when your domain names use our MX records. The last mentioned choice is the most secure one, but you can use it if we manage the e-mails for your domains and do not use some other e-mail 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 as standard with all our semi-dedicated servers, offers you an incredibly easy-to-use interface to enable the SPF security service for every domain name that you host in your new account. Just a few clicks in the Emails section of Hepsia are enough for that and you'll only have to enter the hostname and the IP address of the mail server that will be allowed to send messages from your email addresses. When the email messages are managed by us and not by another provider, you are able to boost the security level even further and activate an option for all of the outgoing email messages to be sent only if your domains feature our MX records. This option will give you more control and it'll eliminate any possibility of anyone counterfeiting your e-mail addresses with the intention of spamming or scamming people. It's not applicable when just your website is hosted on our cutting-edge cloud web hosting platform, while your e-mails are managed by a different provider.
