After I have upgraded from 7.1.6 to 7.5.1 with qmail-scanner from Turtlle, the server stoped responding. All went well until the new plesk instaled the qmail part, 5-10 minutes later it became slower and slower. The comand TOP showed many Qmail-scanner processes on memory. And the load was 120 My server provider, said that the problem was no the program using too much memory !! I had to uninstall qmail-scanner (it took ages) and the load became normal. But now qmail isn't working has it should, no send nor receive e-mails. I am waiting for a reply from Plesk Assistance.... not the fastest dow! Any help on reinstaling Qmail on Plesk ?
