postfix-users: Spam to a "submail" via recipient_delim

Spam to a "submail" via recipient_delimiter

Hello,
i used to create on-the-fly mail-addresses with "recipient_delimiter"
set to "."

Now, one of those mail-addresses is heavily receiving spam.

As this mail-address is of the form "user.sub@...", cannot just remove
the user "user.sub" from my list of users.

I would like to reject any mail to "user.sub@..." as early as possible
while still allowing mail to any other "user.sub2@..." or "user@...".

So far, i could only find "check_recipient_access" that points to a file
contains addresses to be rejected.
But as far as i can tell, this is already quite late in processing the
mails!

Is there any other way to reject/tarpit such "sub-mail-addresses" (from
recipient_delimiter) very very early in processing the mail?

At best, directly after reading the first header-line ...

Thank for any hint!
