Indeed. alias processing happens in the local(8) delivery agent.
If you want to filter mail that late, you will need to use some
external program as mailbox_command. This program runs as the
recipient AND it delivers to the mailbox store.

Use a mailbox transport that talks via SMTP or LMTP to amavisd-new.
Amavisd-new talks to spamassasin and delivers the result via LMTP
to Cyrus.
