Internally, means "internally by Postfix".

An auto-reply from Dovecot is not generated internally by Postfix.

P.S.
In larger enterprise environments, the outbound path is separate
from the inbound path, and bounce notices from the inbound MTA are
best routed through the outbound MTA (whose bounces are in turn
inbound, ...). With DKIM signing on the outbound path, and
verification on the inbound path, bounce messages from inbound mail
can still get signed (if that's desired).
