[Dovecot] Blocked

[Jos Chrispijn]

I have blocked some pop3 user sessions:

Dec  8 00:03:38 xxxxxx pop3-login: Disconnected: user=<johndoe>

Is there a way of sending a message to a user that constantly tries to 
establish a block pop3 session?

Example:

From: noreply at mysite.com
Subject: Your POP3 session
Message:

Hello,
Your POP3 session is blocked; please contact systemmanagement
