Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email, but to look as being sent from a different, ordinarily with the purpose to fraud the recipient for some reason. When SPF protection is enabled for a domain, a special record is created for it in the Domain Name System and all the DNS servers worldwide have it. The record contains all email servers that are permitted to send authentic messages from an address under the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and when the sending server is permitted, the message is sent to the target receiver. In case, however, the sending server is not contained in the SPF record for the particular domain, the email message won't be submitted and it will be discarded. When you employ this solution, it will prevent third parties from sending spam emails that look as if they have been sent by you.
SPF Protection in Shared Hosting
SPF protection can be activated for each domain name hosted in a shared hosting account on our cloud hosting platform with just a couple of clicks. The function is accessible in the Emails section of our outstanding Hepsia Control Panel and all you need to use it is to pick one of your domain names from the drop-down menu and then enter the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers that will be authorized to send emails from your email addresses. As an additional option you may also restrict the messages to be sent from your domain only if it has our MX records, i.e. when our servers handle the e-mail addresses for it, not a third-party provider. This feature offers you the best level of security, but it's not applicable in case only your site is on our servers while your e-mail addresses for the domain are taken care of somewhere else. In either case, the SPF protection service will keep your email addresses risk-free from being used for spam or scam purposes.
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 security service for any domain name in the account with only a few clicks. This can be done from the Emails section of our Hepsia Control Panel which is included with the semi-dedicated accounts and even if you have no previous experience with these things, you won't have any difficulties to enable the security. Everything that you'll have to do will be to choose a domain name from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your emails will be sent worldwide only if they are sent from that specific server. If your e-mail addresses are taken care of by our company and not by a third-party provider, you'll also be able to take advantage of an option for emails to be mailed only if the domain name includes our MX records and this is the safest option. If you have any kind of questions related to thisfeature, you will be able to get in touch with our technical support crew 24/7.
