I event tried this solution posted my Mustafa:
----------
sh /script/fixvpop
If the script cannot make a mysql database connection, then you need to reset the connection pamaterers. Then, do the following:
sh /script/fix-program-mysql PASSWORD
sh /script/reset-mysql-root-password PASSWORD
sh /script/fix-all
sh /script/restart-all
With this solution, the vpopmail will be able to connect to mysql database.
