Unread issue fixed. The other one has two causes:
- disk IO bottleneck, as the maildir resource reads the headers from all the
files
- maildir also creates one create job per mail, but only sends this to the
server after all headers were read. 
- maildir resource keeps the read headers in memory

The above results is first high IO load in the resource, then high CPU load in
the server and the database process, then high IO and CPU load in the database.
This also causes high memory usage by the maildir resource if the read folder
contains a lot of files.
