Mustafa emails now work properly. It helped:
'chmod -f 4755 /home/vpopmail/bin/vchkpw' after ' and 'sh /script/fixmail-all'
Still remained the problem of 'sh /script/cleanup' and the directories with names of customers.
And please do not write because for me there is no problem, because it does not mean that others do not have this problem.
I would ask for a solution to this too.
