Re: corrupted mailboxes.db

Hello,

in case anybody interested, I managed to fix mailboxes.db by this 
technic (I have no shared folders, groups, complex permissions etc)

1. create plain dump file:
  cyr_dbtool /mailboxes.db twoskip show | perl -n -e 'if ( 
~/^([^\t]+)\t%\(A %\(([^\s]+) ([^\)]+)/ ) { print "$1\t0 default 
$2\t$3\t\n"; }' | sort -u >mailboxes.dump
2. import:
  ctl_mboxlist -u <mailboxes.dump

Looks simple, works well

Best,
Deniss
