There are some trade offs with cdb and mysql. Here are some rules of thumb I use when deciding 1) Single machine, no domain over 5,000 users ---> use cdb 2) cluster of machines or more than 5,000 users in one domain --> mysql 3) other systems use mysql and want to interface with vpopmail via mysql ---> then use mysql Ken Jones
