You don't have to use multiple instances if your configuration is
very simple. Multiple instances simplify complex configurations by
breaking them up into more manageable pieces. It also becomes easier
to diagnose performance issues with any content filters, when mail
queued in front of the filter is a different queue than already
filtered mail on its way to some remote destination.
If all you have is an SMTP server with some anti-spam RBLs, a single
instance is likely enough. You can add submission on port 587 with
master.cf overrides (as in the commented out example in master.cf),
but complexity starts to rise. You can add an amavisd-new content filter
and complexity increases further. At some point you may find multiple
instances more sane, that pain point is up to you.
Start simple, and add features gradually. There is a steep learning
curve for a novice to deploy a complex production system with no
prior experience.
