cyrille.lefevre> the access seems to be only for domains, not users...

It can be used for usernames and complete addresses as well.  However, for
blocking incoming addresses, you need:

FEATURE(`blacklist_recipients')
		Turns on the ability to block incoming mail for certain
		recipient usernames, hostnames, or addresses.  For
		example, you can block incoming mail to user nobody,
		host foo.mydomain.com, or guest@bar.mydomain.com.
		These specifications are put in the access db as
		described in the anti-spam configuration control section
		later in this document.
