3 instances is
nothing, 10 is likely fine, depending on the smtpd(8)
and smtp(8) process limits limits for each
one. As for 50, that
seems a bit
ambitious. If the machine can host 50 VMs running
Postfix it can handle at least that many
instances on a single O/S.

You might just need to
trailblaze and do the measurements yourself.
