Sender Policy Framework, or SPF, is a validation system, that is designed to stop the so-called email spoofing where an e-mail message is sent from one email address, but to look as being sent from another one, often with the objective to fraud the recipient for some reason. When SPF protection is activated for a domain, a special record is generated for it in the Domain Name System and all DNS servers globally receive it. The record includes all the mail servers that are allowed to send legitimate messages from an e-mail address part of the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and when its sending server is permitted, the message is sent to the target receiver. If, however, the sending server is not included in the SPF record for the given domain, the message won't be forwarded and it'll be removed. Whenever you use this service, it will prevent third parties from sending spam that appear to have been sent by you.
SPF Protection in Cloud Web Hosting
You'll be able to enable the SPF protection service for your domain names with only a few clicks in the Hepsia Control Panel, which comes with all of our Linux cloud web hosting. This is performed via the section bearing the same name and you're able to allow the protection for each and every domain hosted on our innovative cloud platform. Using a really handy interface, all you'll have to type in is the hostname of the mail server which will be accredited to send messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, it is possible to include several servers as well, if needed. In case your emails are handled on our end, you may also employ an even more secure option by placing a restriction that e-mail messages can be sent only if your domain names have our MX records. This option can't be applied in case your website is here, while your email addresses are with a third-party supplier. In either case, the SPF protection option can considerably enhance your online safety and stop others from counterfeiting your email addresses.
SPF Protection in Semi-dedicated Servers
The Hepsia web hosting Control Panel, which is provided with all our semi-dedicated service, provides you with an incredibly easy-to-use interface to activate the SPF security service for each domain that you host in your new account. Several clicks in the Emails section of Hepsia will be 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 out messages from your emails. If the email messages are taken care of on our end and not by some other provider, you will be able to increase the security level even further and benefit from an option for the outgoing e-mails to be sent only if your domains include our MX records. This option provides you with more control and it will eliminate any possibility of somebody faking your email addresses with the objective of spamming and scamming people. It's not applicable when only your website is on our state-of-the-art cloud hosting platform, while your emails are managed by some other provider. If you aren't sure what options to select, our tech support team will help you 24/7.
