Hello Jérémy, i have had the same problem at one of my hosts and was able to reproduce the error above.
Metche follows the symlinks at "/etc/postgresql/8.2/main" and try to report every difference via email. But one of my colleagues has disabled the cron job, two months ago. The consequence is a 2.1 GB large file at "/root/sent" which could not be handled by mutt. I tried to set a new stable state by running "/usr/sbin/metche stabilize", but nothing happened. So i moved the files at "/var/lib/metche" and executed "/usr/sbin/metche cron". Now everything seems to be fine, but maybe you should realize something like a size check. Regards, Dennis Hoppe
