Unfortunately I also found a server having problem with it. That's why I
have removed the new package again.
In my case one imapd process was in a loop consuming gigabytes of memory
until it was killed by the kernel. This happened again and again.
I attached an strace to the process but lost it's output for some stupid
Maybe I can reproduce it later and provide some more information, or Ken
alreasy knows what the problem is.
