The task was set: to store all mail from the Postfix + CentOS mailer for six years.
We looked at the statistics of the server - on average, a total of about 25 GB per week comes and goes to the server. By simple calculations:
25 GB * 4 weeks = 100 GB per month
100 GB * 12 months = 1200 GB per year
1200 * 6 years = 7200 GB of email messages over 6 years.
We round up for RAID 5 and for an increasing amount of information and we get a storage volume of about 10 TB.
How to organize the storage of such a volume of information? Also concerned about the question: how to configure Postfix so that users cannot delete messages from the server?

Take some server with the right amount of disk space.
You shove messages into the database (Postgre/Mysql) and store them there.
Postfix, in principle, can be told to define a client (not a person, but a program) and work only with its client, in which there is no "Delete" button =)
