imap = 100% CPU Belastung

Hi,

ich habe bemerkt, das IMAP bei mir dauernd 100% CPU LAst verursacht.
Da ich 2 Kerne habe, habe ich das "Glück", das ich es so nicht direkt bemerke.
Aber dennoch würde ich das ganze gern beheben:

TOP => siehe Anhang

Das verursachende Email Konto hat aber nur 4,1 MB im Eingang.
Code: 
36K     ./.Junk-E-Mail
12K     ./new
4,3M    .
4,2M    ./cur
4,0K    ./tmp

4,1 MB bzw. 190 Datein. Ich kann mir nicht vorstellen, das bei einer solch geringen Menge der IMAP-Dienst schon an seine Grenzen stößt.

Kann einer Helfen ?

In der dovecot.conf für den Dienst IMAP hab ich nur folgendes drin:
Code: 
protocol imap {
  mail_plugin_dir = /usr/lib64/dovecot/modules/imap
}
