I'm using Cyrus on a Debian box, with pop3s. I found some time ago that
someone was able to place a spamming tool in the /var/spool/cyrus/
directory. I cleaned it and changed all my passwords. All seemed ok.
I figured out this week that an IRC bot was at the same place. I changed
my passwords again, and upgraded to the last Cyrus Debian package.
It looks like the cracker gained root access. I don't have the time and
window to reinstall my system. My question would be : have you already
heard of such breaks ?
The Cyrus account has shell access in passwd. Is it necessary ? Could I
put it to /bin/false, and change it when I want to su to it for changing
