attacks with rulEmail technology has been around for 58 years and has gradually evolv from simple message delivery over the network to a complex communication tool. Unfortunately, email messages have often been misus to send spam and scams. As a result, protection mechanisms have been develop, but they can be complex to set up. Statistics show that a large number of users do not know how to set up email servers correctly. Fortunately, there is a solution – entrust your mail to the professionals!
Email is prone to abuse from the start.
One of the main problems is the ease of spoofing the sender. It’s easy to set any sender name, such as the name of a company director, and send an email with a fake money transfer order. It is up to the email server administrator to prevent such sender spoofing, which is usually possible.
Another problem is the security of transmitt information. An e-mail message is text without any protection that travels over the Internet. Even if it travels over an encrypt channel, you have no control over whether all server operators along the route also use encryption. The content of the message is not protect by a password or encryption, which may compromise its security. However, the user can increase this level of protection by using an electronic signature or encrypting messages using an S/MIME certificate.
The last problem is spam

If the server administrator does not know how to effectively fight against spam, it may happen that you will either receive too many unsolicit messages, or on the contrary, an important message will be mistakenly mark as spam and you will not receive it.
Email server security and their use
There are several email server security methods that can help minimize the risks associat with email communication. Some of these methods include:
SPF (Sender Policy Framework): SPF allows you to define a list of servers that are authoriz to send emails russia phone number data on behalf of a particular domain. This can ruce the risk of spoofing the sender and marking messages as SPAM.
DKIM (Domainkeys Identifi Mail): DKIM is us to verify the authenticity of the message and its what to put on a resume immutability. Cryptographic keys are us to sign the message, allowing the recipient to verify its authenticity and integrity.
DMARC (Domain-bas Message
Authentication, Reporting, and Conformance): DMARC combines SPF and DKIM mechanisms and provides additional configuration options. An email server administrator can use DMARC to determine how to deal with email that has not been properly authenticat. This mechanism allows better control over message delivery.
Now let’s see how the use of the above mention mechanisms is widespread in the Czech Republic and whether it is us correctly. The statistics are bas on messages that were deliver to the mail servers of ZONER as in the last month . These by lists are therefore statistics.
