Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called e-mail spoofing where an email message can be sent from one email address, but to look as being sent from a different one, often with the objective to fraud the recipient in some way. When SPF protection is activated for a domain name, a unique record is made for it in the Domain Name System and all the DNS servers worldwide have it. The record contains all of the e-mail servers that are allowed to send authentic messages from an email address part of the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and in case the sending server is authorized, the message is forwarded to the target destination. When, however, the sending server is not included in the SPF record for the given domain, the email message will not be sent and it will be removed. In the event that you employ this solution, it will stop third parties from sending spam e-mails that seem to have been sent by you.
SPF Protection in Cloud Hosting
You are able to activate the SPF protection service for your domains with a few clicks from the Hepsia Control Panel, which is included with our cloud plans. This is performed from the section bearing an identical name and you are able to set up the protection for each domain part of our state-of-the-art cloud hosting platform. Using a very simple interface, all you will need to type in is the hostname of the mail server that will be authorized to send messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you'll be able to include several servers too, when needed. In case your emails are taken care of on our end, you can also employ an even more secure option by setting a limit that e-mail messages can be sent only when your domain names feature our MX records. This solution can't be applied in case your site is hosted here, while the email addresses are with some third-party supplier. In either case, the SPF protection option will really enhance your online security and stop others from counterfeiting your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from our company, you'll be able to secure your email addresses by enabling the SPF protection service for any domain name in the account with just a couple of mouse-clicks. This can be done through the Emails section of our Hepsia Control Panel that comes with the semi-dedicated accounts and even in case you have no previous experience with such issues, you won't have any kind of problems to enable the security. The only things that you will have to do will be to choose a domain from a drop-down menu and after that type the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your email addresses will be mailed globally only if they were sent from that specific server. In case your e-mail addresses are taken care of by us and not by some third-party supplier, you can also use an option for e-mail messages to be sent only when the domain name has our MX records and this would be the safest option. Should you have any kind of questions regarding thisfunction, you will be able to get in touch with our technical support crew 24/7.
