Your internal users can use an MSA and mailstore front-end MTA that
are not the same as your Internet-facing inbound gateway. This
allows a larger message size for purely internal email.
You can also operate separate inbound and outbound MTAs (or just
Postfix instances) with separate message size limits, if it somehow
makes sense to allow larger mail out than in. Generally, that's
probably not a good idea.

Most people don't use "mbox" files these days, so the issue is
largely moot. With pipe delivery via dovecot LDA, just make sure
the mailbox_size_limit is large enough to hold one message.
With LMTP, it is not Postfix that controls file size limits.
