-ERR [SYS/PERM] unable to open maildrop

[Morten Trab]

This is all I get when I try to connect to my Cyrus POP3..   It all appeared after I had a mailbox.db error, which I apparently got cuered by running ctl_cyrusdb (I think), but now it keeps rejecting the passwords for every account on the system...   What've gone wrong, and how do I solve the problem??   Best regards and TIA,      Morten Trab, Denmark
