It does assign the PID and they do rollover. There's only 32K of them,
which isn't too many on some systems. My incoming email systems rollover
several times a day, but those are short lived sendmail and various
scanning processes.
Most programs needing many short-lived processes use a pool to avoid
the performance hit of creating many new processes. The performance
hit depends on the threading model; some are optimized so a new
process is faster than a new thread. I am unaware of a modern MTA
that creates a new process for each message.
[Richard: This is an RFI. I hate ignorance, especially my own. What
MTA is used?]
Sendmail 8.13. Here's my PID list for sendmail at the moment. Granted
some are the parents, queue runner, some are hung open, etc. But it most
certainly isn't using a pool. And it would be for each connection, as
multiple messages can be sent through a single connection.
