Milter-greylist

Hi,

I've got four MX servers and observed strange behavior of milter-greylist.
Please, see the fragments of databases (dumpfiles) below of each servers:

# server1
1.2.3.4 <sender@...> <recipient@...> 1527324170 # 2018-05-26 10:42:50

# server2
1.2.3.4 <sender@...> <recipient@...> 1528536443 AUTO # 2018-06-09 11:27:23

# server3
1.2.3.4 <sender@...> <recipient@...> 1527324170 # 2018-05-26 10:42:50

# server4
1.2.3.4 <sender@...> <recipient@...> 1527324170 # 2018-05-26 10:42:50

It shows, that serwer2 recived the email and milter-greylist added the flag AUTO. 

After the time of 8 hours (because of timeout=8h), this information contains server2 only:

# server2
1.2.3.4 <sender@...> <recipient@...> 1528536443 AUTO # 2018-06-09 11:27:23

So, at this situation, when the sender will start sending second email (the parameters: IP, sender, recipient are still the same) and connects to server3 or serwer1, or server4 it will be wait.

From my point of view, waiting in such situation is a nonsens. 

Why the information abut 'autowithe' isn't distributed over all MX servers?


P.S
All my config files are as follow:
