Yes. But I'll give this a try:

unfortunately with the same result:

root at mail:~/cyrus-debug# /usr/lib/cyrus-imapd/ctl_mboxlist -d >
root at mail:~/cyrus-debug# vi /tmp/mboxlist.txt
root at mail:~/cyrus-debug# /usr/lib/cyrus-imapd/ctl_mboxlist -f
/tmp/ -u  < /tmp/mboxlist.txt
fatal error: failed to mmap /tmp/ file
root at mail:~/cyrus-debug# ls -l /tmp/*
-rw------- 1 cyrus mail 2219712 Apr 22 22:06 /tmp/
-rw------- 1 cyrus mail   11400 Apr 22 22:06 /tmp/

I found the cyr_dbtool command.

Is the "cyr_dbtool delete key" maybe meant for this too?
