Same situation here! I have googled a lot, but I have come across a lot of confusion...

The courier-maildrop debian package installs maildrop v1.7.0, but has no mysql support; This means you couldn't determine the destination directory when delivering mail through maildrop. So maildrop must be compiled from source... mmh... from maildrop v.1.8 on, mysql module has been removed from source, and replaced with Courier Authentication Library, here: <http://sourceforge.net/project/shownotes.php?release_id=80275&group_id=5404>.

I have found no clear howtos nor indications on the Web about using the suggested Courier Auth Library!! I don't even know if the CAL+mysql method is available under maildrop 1.7: It would be great because I could configure the debian maildrop package with CAL and upgrade via apt one day without messing up things!

I have found this page: <http://www.xs4all.nl/~jaspersl/quota/> The author claims his tutorial integrates smoothly with Haas', but his explanation is so 'squeezed' that I can't fully understand the reasons behind some of his directions. He compiles maildrop from source, but uses an old version (1.6.3), this way he can rely on the deprecated mysql support at compile-time. I don't like that much because you are forced to stay away of apt-get and not to upgrade maildrop in the future.

I have contacted Chris Haas, and he said he's been is in contact with the Courier package maintainers. The "experimental" branch of Debian actually lists a current "maildrop" and "courier-authlib" packages. It's rumored to be very stable already. I haven't tried that, and leave it up to the brave-hearted... :-)
