If you are using vpopmail 5.4.30 and you get this error client_connect:_warning:_config_begin_failed/Aack,_child_crashed._(#4.3.0)/ or client connect: warning: config begin failed/Aack, child crashed. (#4.3.0) maybe you have to try this: cat > ~vpopmail/etc/vusagec.conf << __EOF__ Server: Disable = True; __EOF__ In this way you could correct the error and save your strength for something better.
