Thanks for your help and so quickly :)

I decided to try with current version of postgrey
from projects github repository.
as I want to avoid using more 3rd party repos.

Doing the first steps in manual installation
(create directory and user) I found out, 
that I lack from knowledge on "ls" output..

There is a difference that I don't understand.

What does the "." at the right side 
of the attributes list mean?

directory manually created on the shell:
drwxr-x--x 2 postgrey postfix 4096 Apr 22 17:19 /var/spool/postfix/postgrey/

created by package installation:
drwxr-x--x. 2 postgrey postfix 4096 Apr 13 16:23 /var/spool/postfix/postgrey

I used this commands to create the first one

# mkdir /var/spool/postfix/postgrey
# chmod 751 /var/spool/postfix/postgrey
# groupadd --gid 493 postgrey
# useradd --system --gid 493 --uid 493 --home /var/spool/postfix/postgrey -M --shell /sbin/nologin postgrey
# chown postgrey /var/spool/postfix/postgrey
# chgrp postfix /var/spool/postfix/postgrey

Can you give explanation what is causing the difference
compared to the package created directory?
