Virtual User Authentication

I have only "virtual users" on the system that I maintain. I am using Postfix
which is configured to use Devecot for authentication. I get several attempts
everyday to hack into the system, both via Postfix and directly via Dovecot.
The following is from the dovecot log:

Nov 11 04:14:48 auth-worker(21005): Error: pam(monica,
pam_authenticate() failed: authentication error (/etc/pam.d/dovecot missing?)

Now, I do not use "pam" on this system. Is there a way I can eliminate
Dovecot from trying to use it?
