We are getting these message every day since a few month:
I can't find any help or solution ... the system is working.Error: found unknown arguments on the command line ('').
Reprocess mails from spool directory that could not be imported in the first
[--help] - Display help for this command.
[--no-ansi] - Do not perform ANSI terminal output coloring.
[--quiet] - Suppress informative output, only retain error
Maybe i found the error ... the first params field is expanded, i just clicked "-" and now it looks like the others.
