Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called email spoofing where an email message is sent from one e-mail, but to seem as being sent from another, typically with the idea to scam the recipient for some reason. If SPF protection is activated for a domain, a special record is made for it in the Domain Name System and all the DNS servers globally get it. The record includes all mail servers that are allowed to send legitimate messages from an email address part of the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and if the sending server is permitted, the message is forwarded to the targeted destination. When, however, the sending server doesn't exist in the SPF record for the specified domain, the e-mail message won't be submitted and it will be removed. In the event that you employ this service, it'll prevent third parties from sending spam messages which look as if they have been sent from you.
SPF Protection in Cloud Website Hosting
If you host your domain names in a cloud website hosting account on our end and we handle the e-mails for them, you are able to activate SPF protection for any of them with several clicks in your Hepsia Control Panel. The service can be found in a section of its own where you are able to view which domains are currently protected. For those that are not, you can activate the SPF protection solution and manage a lot of things at the same time - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that messages can be sent only if your domains have our MX records. The last mentioned choice is the most secure one, but you can use it in the event that we handle the email addresses for your domains and you are not using some other e-mail supplier. The newly generated records will be activated within 1 day and nobody will be able to forge the FROM field in an e-mail using your e-mail addresses.
SPF Protection in Semi-dedicated Servers
The SPF protection function is provided with all of the semi-dedicated servers, so in case you host your domain names in an account on our cloud web hosting platform, you are able to use this particular service without difficulty for any of your domains. The Hepsia Control Panel, which comes with the semi-dedicated accounts, features a really user-friendly interface, therefore you do not have to be proficient in the use of computers to secure your emails. You'll only have to type the hostname and the IP address of each mail server that you would like to be permitted to send out e-mails from your addresses and right after that the new record will be activated for the domain that you have picked. As an additional option, we'll also allow you to limit the outgoing e-mail messages and secure your mailboxes even further by allowing email messages to be sent only if the domain name in question includes our MX records i.e. the e-mail messages for the domain name need to be managed by us and not by a different company. Doing so you will have even better control and there won't be a chance for anyone to forge your email addresses for harmful activities.
