Each Postfix SMTP server process handles one remote SMTP client at
a time. The number of processes can be zero up to an including the
process limit for that service.
With a larger process limit, Postfix can handle more remote SMTP
clients concurrently, before it logs that the SMTP service "has
reached its process limit".
Keep in mind that STRESS_README.html describes a number of conditions
that may result in this warning. For example if DNS lookups are too
slow then fixing DNS is more effective than configuring a larger
process limit.
