What is virtualization and how does it benefit your server

Server virtualization masks server resources from server users into individual virtual private servers with their own operating system. Servers get isolated from the OS of the other servers hosted on the master physical machine known as the host. So, what is virtualization?

What is an SPF Record?

by
What is an SPF Record?

SPF or Sender Policy Framework is a DNS record that indicates mail exchanges in which hosts are authorized to send mail for a domain. An SPF record is a type of TXT(text), and its purpose includes essential notices regarding the domain. They are used because the SMTP protocol does not authenticate the “from” address in an email. Without it, attackers may easily impersonate the sender’s email address. This works so that the attackers or spammers can edit the From address to make it look like they are sending from an email address to your domain. This action is also known as email spoofing, which uses the user’s private information and can decrease the reputation of the IP address where the domain is pointed, which may lead to blocking. That is why using the SPF record is crucial when configuring the domain.

The SPF record can be managed via the domain’s DNS zone. This information is mostly handled by system administrators who have access to the user’s domain’s DNS zone. The SPF record has its format, mechanisms, and modifiers, which will be explained in more detail in the next paragraphs.
