It is just overly complex under the hood. This is one of the beauties of OpenGroupware - it's just PostgreSQL and the filesystem. Simple and clean; PostgreSQL 8.3 performance is very good. And you just reuse whatever SMTP/IMAP architecture you have or want, this a strong bias towards Cyrus (of course). That is how it should be, IMHO, subsystems should be loosely coupled; but it does make it more difficult to implement some features.
