Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called e-mail spoofing where an e-mail message is sent from one e-mail address, but to seem as being sent from another one, frequently with the objective to fraud the recipient in some way. If SPF protection is activated for a domain name, a specific record is created for it in the Domain Name System and all DNS servers worldwide get it. The record includes all of the e-mail servers that are allowed to send valid messages from an e-mail address part of the domain. When an e-mail is sent, the first DNS server it goes to verifies the SPF record and in case the sending server is authorized, the message is sent to the target destination. When, however, the sending server is not included in the SPF record for the given domain, the e-mail message will not be sent and it will be discarded. If you employ this service, it will prevent third parties from sending spam emails which appear to have been sent from you.
SPF Protection in Cloud Web Hosting
If you host your domain names in a cloud web hosting account with us and we handle the email addresses for them, you are able to activate SPF protection for them with a few clicks in your Hepsia Control Panel. The service can be found in its own section where you will be able to view which domains are already secured. For those that aren't, you will be able to enable the SPF protection solution and set up a variety of things at the same time - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, and even to set a rule that emails can be sent only when your domain names have our MX records. The last mentioned option is the most secure one, but you can use it in the event that we handle the emails for your domains and you're not using some other e-mail supplier. The newly generated records will propagate within a day and nobody will be able to fake the FROM field in an email by using your addresses.
SPF Protection in Semi-dedicated Servers
The Hepsia web hosting Control Panel, that comes as standard with all of our semi-dedicated plans, provides you with an extremely easy-to-use interface to activate the SPF security service for any domain name that you host in your new account. Several clicks in the Emails section of Hepsia are enough for that and you will only have to type in the hostname and the IP address of the mail server that will be permitted to send out messages from your emails. In case the e-mails are handled on our end and not by a different supplier, you'll be able to boost the security level even further and benefit from an option for the outgoing email messages to be sent only if your domains use our MX records. This option will give you more control and it will eliminate any chance of anyone faking your e-mail addresses with the purpose of spamming or scamming people. It's not applicable if only your site is hosted on our innovative cloud hosting platform, while your e-mail addresses are managed by a different service provider. If you are not sure what features to pick, our tech support crew will help you 24/7.
