That is impossible, there is more than 1TB of free space on the zfs pool where
postfix queue is allocated.
If I had so little space, I would have ran into other troubles long before this
strange problem.
This system is delivering continuously 24/7 thousands of email per day.
This is something that started to happen sporadically in the last few months,
after year of works.
What may be misleading Postfix about my available space?

warning: not enough free space in mail queue: 38384640 bytes
This last warning looks quite uncomprehensible, message size limit is
50000000, and sure 38384640 is less than 1.5*msl, so what's the problem?
_that_ is apparently the problem.
you have 38384640 B (~38MB) of free space in queue, but message maximum size
is 50MB, so you don't have enough of free space for maximum message size,
not even for 1.5*maximum required by default:
