So, this changes the size limit as reported by the Postfix SMTP
server. As of a few releases ago, the SMTP server will also enforce
the size limit, to avoid wasting resources sending too large mail
to a before-queue content filter.

Indeed. The cleanup server implements the message size limit. In
early Postfix days, this was the only place where the message size
limit was enforced.

The message says that the queue file exceeds the size limit.
The message has nothing to do with free disk space.
