There seems to be a problem with your caps-lock key.
Since it seems that you said that you are using maildir for your mail
server, it is likely very useful if you do enable even rather mild
compression (e.g. lz4) since this will reduce the write work-load and
even short files will be stored more efficiently.
FYI, a couple of our big zfs mailspools sees a 1.24x and 1.23x compress
ratio with lz4. We use Maildir format as well. They are not RELENG_13
so not sure how zstd would fair.
