Not needed. The Postfix SMTP server logs this with verbose mode
turned on:
msg_info("%s: blocks %lu avail %lu min_free %lu msg_size_limit %lu",
myname,
(unsigned long) fsbuf.block_size,
(unsigned long) fsbuf.block_free,
(unsigned long) var_queue_minfree,
(unsigned long) var_message_limit);
That is, it logs the file system blocksize, the number of free
blocks, and the "queue_minfree" and "message_size_limit" Postfix
parameter values.
Based on these, it decides if the number of free blocks is more
than queue_minfree, and if the message size limit in blocks is less
than the free blocks/1.5.
