Yes, we had enable it on Maildir/ without problems.

We had created a custom script but you can find many example on the web:

I suggest to do not use script that rename email files because they can 
invalid the uidlist. Simple check if the file is already compress (es. 
if gzip -t "${MAILFILE}" 2> /dev/null".
