MAINTAINING STATE
There are four basic groups of filtering functions:
1 filter_relay
2 filter_sender
3 filter_recipient
4 filter_begin, filter, filter_multipart, filter_end
Group 4 would all be the same perl process for any one message. You
can set a global in filter_begin() and use it in filter().
However a global needs to be reset before the next message is handled!
I put the resets together in a stanza at the top of filter_begin().
