hi paul,

yes, it's a spam defense method, but there are different opinions about 
that; my company stopped using greylisting as it increases the load on 
the senders MTA.

however, usually there is a 'timeframe' mentioned in the maillog (at 
which you had a look, as you wrote earlier).

you can speed up the process of becoming a 'legal' MTA; e.g., when you 
sent an email at 10:00pm and the greylister said 'try again in 7 
minutes, then re-queue your email at 10:08pm and it will go through 
immediately as every email you send from now on will -- as you are 
'whitelisted' for you MTA's IP address from now on.

however, if you have a non-static IP address on your MTA, this problem 
will occur after every disconnect/new assigned IP address.

HTH,

timo

ps: i'd recommend to pull every stick out of your SS5, clean the sockets 
with compressed air (don't touch them), and reseat the memory sticks. 
maybe corrosion, dust or something causes trouble.
