No. 10025 is a port Postfix is listening on and where amavisd-new sends
the mail after it processes it.

10024 and 10026 are the ports amavisd-new listens on and is where
Postfix sends the mail to amavisd-new for processing.

Postfix -> amavisd-new 10024  -> Postfix 10025
        -> amavisd-new 10026

Mail is normally submitted to amavisd-new on port 10024:
content_filter = smtp-amavis:[127.0.0.1]:10024

but by sending it to port 10026 instead, amavisd-new is able to
differentiate the two. It is this ability that makes the policy bank
possible.
