Sender Policy Framework, or SPF, is a verification system, which is intended to prevent the so-called email 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 purpose to fraud the recipient in some way. If SPF protection is activated for a domain name, a specific record is made for it in the Domain Name System and all DNS servers globally have it. The record contains all the mail servers that are allowed to send legitimate messages from an email address part of the domain. When an email is sent, the first DNS server it goes to checks the SPF record and if the sending server is permitted, the message is sent to the targeted destination. In case, however, the sending server is not contained in the SPF record for the specified domain, the e-mail message won't be forwarded and it will be removed. In case you employ this solution, it'll stop third parties from sending spam that look as if they have been sent from you.
SPF Protection in Shared Web Hosting
When you host your domains in a shared web hosting account on our end and we handle the e-mails for them, you will be able to activate SPF protection for all of them with several clicks inside your Hepsia Control Panel. This service is accessible in its own section where you are able to see which domains are already protected. For those that are not, you can enable the SPF protection option and configure numerous things in the process - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, and to set a rule that emails can be sent only if your domain names include our MX records. The last mentioned solution is the most secure one, and you can use it if we take care of the emails for your domain names and you are not using another e-mail supplier. The newly generated records will be activated within a day and nobody will be able to forge the FROM field in an email with your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from us, you are able to secure your emails by activating the SPF protection service for any domain name hosted in the account with just a few mouse-clicks. This can be done from the Emails section of the Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you have no previous experience with these matters, you won't have any kind of trouble to activate the protection. All that you will have to do will be to choose a domain from a drop-down menu then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be sent globally only if they were sent from that particular server. In case your e-mail addresses are handled by our company and not by a third-party provider, you will also be able to activate an option for emails to be sent only if the domain includes our MX records and this would be the safest option. Should you have any questions related to thisfeature, you'll be able to contact our technical support crew 24/7.
