No, fix-qmail-assign not related to 'rpm -q qmail-toaster'.
So what should I do to make it work ?
I've copied to clean system /home/lxadmin/domains and vpopmail, kloxo mysql databases, chown -R them for mysql:mysql and copied all users files like /etc/passwd etc. and restarted mysql then runned /script/fixmail-all and it happens.
There are a lot of non-existing domains is my vpopmail database how to clear them ?
