Execute a script from dovecot when authentication fails

Hello,

My name is Noury, and I?m new here.
I?ve been using dovecot IMAP for years, but I want to do now some extra things.

I want to call a script from within dovecot, to build a suspicious IP addresses
list when authentication fails.

I have tried the PostLoginScripting technic. It works fine but it doesn?t suit
my needs. The script executes only after a successful login.
I want to execute my script only when auth fails. If I can execute a script and
check into it if auth failed, I would be nice too.

A kind of ? PreLoginScript"

Is there a way to achieve this?
I?m reading now auth.log file, but I would like to have a realtime processing.

Thanks in advance.

Noury

   It's probably easiest way to do this.
