How to remove postgrey at all

I removed it from everywhere but it still keeps on greylisting.

The following line:

 check_policy_service inet:127.0.0.1:10023

is removed from

 smtpd_recipient_restrictions =

in

 /etc/postfix/main.c

and I also disabled all the files in /etc/default/postgrey and /etc/postgrey by commenting them all out inside and giving the files different names too but... it still keeps on greylisting like this (it shows in my logs):

 postgrey[4196]: action=pass, reason=triplet found...

Could anybody advise me please, how the heck do I remove this postgrey at all? I would highly appreciate it before I go completely nuts at it. I am also thinking that perhaps it's because of the entries that are left out somewhere because postgrey says the following (in /etc/default/postgrey),

"--max-age=N delete old entries after N days (default: 35)". 

Now where are these entries kept and how do I delete them? That is the only reason I can come up with as to why this thing keeps on greylisting.
