Now supported by v2.0. Also as a patch to v1.2: http://dovecot.org/patches/1.2/zlib-compress.diff
I'm not really sure if I should commit it to v1.2 code tree. The code contains ugly copy&pasted io_stream_copy() and v1.2 is supposed to be feature complete..
In would sure like to see that feature in stable 1.2. It is optional and in a plugin, so quite unlikely to harm. And you could even require a configure flag for it.
If I could enable it per user, it would be perfect, but current is already nice to have. We have some customers who like to keep their mail data forever, and compressing on the fly would be much nicer than a nightly cron job. :)
