After Postfix gives the message to the content filter, the filter
can do all kinds of things. It can give the message to another
content filter (for example over SMTP), or send the message to
Postfix, or send the message to a different MTA, or it can even
discard the message. Those are all valid actions. There is no need
for Postfix trying to be clever and get in the way of things.
In particular with SMTP-based filters, there is no need for clumsy
wrapper scripts. Simply configure each filter to send the result
to their successor's SMTP port.
