So they sail over the world and because of the time difference we
can't help them ride away.
I believe you should clarify or remake your test model, there is
something I'm not sure to understand:
- is a single ship likely to generate +40K email messages in an hour, or
does this high figure applies to the postfix that will receive all
messages from all ships?
- do you account for the latency of offshore internet connection
(satellite?) in your test?
Also, to my experience high throughput email servers are heavily
dependent on storage IO: you might find out that every other server
performs OK on your virtualization node and still get an IO bottleneck
in your email server.
Finally, like Wietse wrote, postfix does not lose email. Worse case
scenario: your OS lose files. Normal scenario: postfix refuses email it
can't ingest with temp error, sender retries later.
