It stores the messages in plain text each in it's own file (like maildir) but then it also indexes the headers in bdb format and also can index the search database in bdb format. The result is a very simple mail store that can perform searches very fast. The only problem is that the search index in only updated periodically. If you need more information then look at the cyrus-users list as this is WAY off topic. schu
