Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called email spoofing where an email message is sent from one email address, but to appear as being sent from a different, generally with the idea to fraud the recipient in some way. If SPF protection is enabled for a domain name, an exclusive record is created for it in the Domain Name System and all of the DNS servers around the world get it. The record contains all the mail servers that are permitted to send legitimate messages from an address within the domain. When an e-mail is sent, the very first DNS server it encounters checks the SPF record and if its sending server is authorized, the message is forwarded to the targeted receiver. When, however, the sending server is not present in the SPF record for the specified domain, the e-mail message won't be submitted and it'll be removed. When you use this service, it will stop third parties from sending spam messages that appear to have been sent from you.
SPF Protection in Shared Hosting
You'll be able to enable the SPF protection option for your domain names with only a few clicks from the Hepsia Control Panel, which comes with our Linux shared hosting. This is performed through the section with the very same name and you can set up the protection for any domain part of our cutting-edge cloud hosting platform. Using a very convenient interface, all you will need to enter is the hostname of the mail server that will be permitted to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, it is possible to add several servers as well, when needed. In case your email addresses are taken care of by us, you can also employ a more risk-free option by setting a restriction that messages can be sent only when your domain names include our MX records. This alternative cannot be applied in case your web site is hosted with us, while your email addresses are with some third-party supplier. In either case, the SPF protection option can really improve your online protection and stop other people from forging your email addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from us, you will be able to protect your emails by activating the SPF protection service for every domain in your account with just a few clicks. This is done in the Emails section of the Hepsia Control Panel that is provided with the semi-dedicated accounts and even in case you have no previous experience with these kinds of issues, you won't have any difficulties to enable the protection. Everything that you'll need to do is to pick a domain name from a drop-down menu and then type in the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your email addresses will be mailed worldwide only if they were sent from that server. When your email addresses are managed by our company and not by a third-party supplier, you'll also be able to activate an option for emails to be mailed only if the domain name contains our MX records and the aforementioned is the most secure option. When you have any kind of questions about thisfunction, you can get in touch with our support crew 24/7.
