Neither the grsec.log nor dmesg said anything special.
The box had filesystem issues a month ago. I sucessufly fscked it. Do you think its a hidden fs problem or a dovecot issue?
Here in Germay the time is at 0:30, I'll sleep some hours until I can respond to "need more information request (conf-file, or so)"
Thx in advance!
