No.

The rules are:

- Anything you set outside a subroutine in your filter is available all
the time.

- Anything you set inside filter_relay, filter_sender or filter_recipient
is volatile -- it may or may not be set for any other functions.  See
the source code to understand why. :-)

- Anything you set in filter_begin is available in filter and filter_end.

- Anything you set in filter is available in filter_end.

David.
