reworked online_detect to the simpler online_query
Only pipe is supported now. Use
online_query="/bin/cat /path/to/file"
instead of
online_detect=file
online_file=/path/to/file
and
online_query="/path/to/some/script foo"
instead of
online_detect=pipe
online_pipe="/path/to/some/script foo"
See man page masqmail.conf(5) and admin/config-transition.
