It is most safe to remove command mail entries from aliases.
Another 2nd best solution follows:
use_command_mail_function = noIn this case, /usr/local/libexec/fml/command runs once but does not work and ends as soon as possible.
The following solution may be possible.
use_command_mail_function = yes command_mail_restrictions = rejectWhen fml receives the incoming command mail, it inform the rejection to the sender in all cases.
This configuration works but it evalutates each line. It is useless.
