You're forgetting connections, I think it is somewhat like
this:

    filter_initialize()

    foreach connection {
	filter_relay()

	foreach message {
	    filter_sender()

	    foreach recipient {
		filter_recipient()
	    }

	    filter_begin()

	    foreach part {
		if ( is_multipart ) {
		    filter_multipart()
		}
		else {
		    filter()
		}
	    }

	    filter_end()
	}
    }

    filter_cleanup()

And independently the filter can call filter_tick, filter_map
or filter_unknown_cmd.

NO! You are missing one very important thing: each call might end up
in a _different_ mimedefang.pl client. See "GLOBAL VARIABLE LIFETIME"
in the mimedefang-filter manpage.
