We are doing exactly this with our gateway MX server. First we replicate the MySQL database then we use rsync running every 30 minutes to just sync the first couple of directory levels from the /home/vpopmail/domains/x/domain.com on the vpopmail server (this picks up the aliases, mailing lists and autoresponder names) and the /var/qmail/users/assign file. chkuser works perfectly at the MX server. SMTPROUTES sends everything to the vpop server. We do virus filtering and spam analysis on the MX server and the balance on the pop server. Basically, we just sync enough over to the MX server so chkuser can work.

This isn't possible with the current version of chkuser. I'm wanting to do
the exact same thing. Vpopmail currently needs access to 1) the
authentication scheme (MySQL in your case) 2) the file system (to check the
~qmail/control files and .qmail- files for aliases and catchalls)

Also, keep in mind that you can set up vpopmail/chkuser to check against the
primary MySQL database. There is no need to replicate it.

I've been told that the Antonio wants to build client/server functionality
into chkuser but hasn't been able to find the time. I for one look forward
to seeing it.
