the zlib_save question reminds me of a wish: I think it's not possible to set zlib_save parameter per namespace (or even mailbox). Per namespace would be something for the wish list to get rid of the cron job method to compress archival mailboxes. And maybe an option to add a "Z" flag to compressed maildir message files as recommended in the wiki regarding compress crob job.

+1 on this request. I have a slightly different use case -- I have both an dbox and Maildir. Incoming email goes to Maildir, but I archive off to dbox (using Thunderbird). After I archive my emails, compression seems like a reasonable choice.

Any idea if this feature will be available at some point?

For v2.2 I'm hoping to have per-namespace mail settings, although I'm not sure if it actually gets implemented - so many other things to do as well. Then (among other things) you could do:

namespace foo { plugin { zlib_save = gz } }
