Milter-greylist

Hi,

Now I got a new problem, there seems to be some servers that doesn't 
retry to send again after the first denial/delay.

Here is my servers log:
Jan 21 20:51:32 www milter-greylist: j0M1pWmB049792: addr 
212.78.202.217 from <test@...> to <macper@...> delayed 
for 00:01:00

daemon=MTA, relay=lmfilto03.st1.spray.net [212.78.202.217]

This is the error that comes to test@...:

Does anyone have ANY clue what is happening ?  It must depend on 
milter-greylist since it is working fine without it.

Sincerely
