Hello everyone, I'm representing a performance problem on my server.
I explain in detail the configuration of my server.
I am using postfix with 46 IPs configured as a mta, with round-robin,
in the master.cf file
46 IPs? why?
thank you for responding, we send transactional mail, we have around
100,000 clients with their respective email accounts.
I think the "cleanup" process is responsible for the excessive use of
cpu.
ps fax | grep -c cleanup
181
the whole fact that there's 181 instances of a process does not mean they
are eating your CPU.
"top" could give you more information.
However, the question is: how many mails does the machine process?

I have modified the maxproc in the master.cf file but the change was
not made.
have you reloaded postfix by issuing "postfix reload"?
