Hi, all!
I need to filter messages, sent by one of users. His messages must have
less recipients (in To:, CC, :BCC fielsa), than some constant value. And
if recipient count is more than this constant, message must be returned
to sender with corresponding note.
I can write an external script, that validates messages, but i cat't plug
it to exim correclty.
If i write (user filter)
# Exim filter
pipe "path-to-script"
then valid messages not delivers, and if i write
# Exim filter
unseen pipe "path-to-script"
then invalid messages does not returns to sender.
exim 3.22
