(only sysop, init.bcm)
Syntax: M_(FILTER) [ <program> | off ]
(default: off)

With M_FILTER a program can be defined in file "init.bcm" which is executed
each time a mail is received. If value is set to "off" this function is
disabled.

This program can examine the mail, e.g. forbidden words etc. The program
must return a value after examining the mail. It depends on the value what
happens with the mail:
  0: nothing happens
  1: the mail will be deleted
  2: the mail is being hold

The return values 1 and 2 are only available using DOS or Windows, not Linux!
So, when using Linux, M_FILTER can only be used to call an external program
without evaluating a return value.

Note: The <program> must contain the whole path!

All M_FILTER calls are logged in file "trace\m_filter.bcm".
