Abstract :
Email spam, email spoofing, and viruses that are distributed via e-mail are
unwanted by e-mail users. Spam e-mail, spoofing e-mail, and e-mail that contain viruses
can cause enormous harm to both service providers and email users. Based on this
background, it encourages the author to apply the DMARC, Anti Spam, and Anti Virus
protocols so that the mail server can avoid spam e-mail, viruses and e-mail users can
avoid spoofing activities.
The design and analysis of the implementation of the DMARC, anti-spam, and
anti-virus protocol uses the NDLC methodology, which is a computer network
development method. Which starts with designing a spam, spoofing, and virus email
filtering system, simulating installation and configuration. The next stage is
implementation where at this stage the system that has been previously designed is
implemented and tested on the spam, spoofing, and virus email filtering system. The last
stage is the monitoring stage where supervision will be carried out on the system that
has been made to determine the level of success of the system that has been created.
The results or outputs to be achieved are that the mail server can avoid spam
emails, email spoofing, and viruses to ensure the security and comfort of email users
and avoid the impact of losses that can be caused by email spam, email spoofing, and
viruses.
