Any chance of getting compression support via the zlib plugin for dovecot deliver in future versions?

Sure, if someone implements it. For me it's a very low priority.

Understood, was also wondering if a patch would be taken upstream for such a feature, that answers that.

Thanks

I can give a few implementation hints:

With v1.2 you should be able to do this completely in a plugin, because maildir saving keeps the output stream in struct mail_save_context.output. You could hook into mailbox.save_begin() where you'll first call the super.save_begin() and then replace the created output stream with a zlib_ostream, which you'll need to implement. Currently the only implemented output stream is src/lib/ostream-file.c.

Actually it sounds like it would be pretty easy to implement after the zlib_ostream is done. I thought it would have been more complex. :)

Thanks for the tips. I think compression via deliver is a much more elegant approach compared to a cron script. I also think such an implementation is less prone to error. With that said, I'm gonna start looking into it tonight and I'll probably be back in touch with questions. :)
