Done.
Steps:
1. Create 'tester' as new client
2. Change owner of nemcio.pl from 'never' to 'tester'
3. Delete nemcio.pl from panel
4. directory '/home/tester/nemcio.pl' and '/home/lxadmin/mail/domains/nemcio.pl'
5. run 'sh /script/fixmail-all' to make sure delete process everything running well
6. Create again nemcio.pl under 'tester' client
7. Add some mail account
8. Change owner of nemcio.pl from 'tester' to 'never'
9. Run again 'sh /script/fixmail-all'
Mustafa now is OK.
Do I performed 'sh/script/cleanup' will also work fine?
Do you know why this error occurred?
Don't worry, cleanup not destruct your mail.
I didn't investigated deeply. It's possible dirs and or files permissions and or ownership. Permissions like 0700, 2700, 4700 or 6700 have different effect.
Fixmail-all script try fix mail issue (fixmail like previous kloxo, set softlimit, fix user-assign, customize custom run, fix vpopmail password and others). This script not exist on previous Kloxo. Sadly, issue like yours still not fixed by this script because some parameters are missing.
Some problems possible because Kloxo-MR maybe have bugs but this bugs possible from others (like qmail-toaster rpms or other packages).
Sometimes, we don't care 'why' but need 'how'.
