I'm not sure how usefull this solution is for other people, but my filter
drops out on local mail which prevents my own generated errors being
filtered. I check for the lack of a reception by (e)smtp which is all my
server uses rather than the existance of a reception by local line in case
that could be forged (like my bounce message could.
if $message_headers does not match "by mymailhost.domain.com with (e|)smtp"
then
finish
endif
