I've got mine set to 30 seconds and the longest delay I've seen during
testing was about 5 minutes. I can say that I have not seen any problems
with large server farms (google, hotmail, yahoo, mindspring) dealing
with the greylist. Nor have I seen issuse from my work, or the various
state agency servers I get mail from friends from. (I'm using the
greylist-milter with Sendmail if that matters.)
To borrow an old line ... You can have my greylist-milter when you pry
it from my cold dead server.. (apologies for the drama) ;-)

I implemented greylist.pl in my environment (~25k messages per day) and
found it to not work well. Many of the large isp's have multiple
outgoing
e-mail servers which results in the following scenario:
Server 1 attempts to deliver from [EMAIL PROTECTED] and is greylisted.
After defined pause Server 2 attempts to deliver from
[EMAIL PROTECTED] and
is greylisted again.
After another defined pause Server 3 attempts to deliver from
[EMAIL PROTECTED] and is greylisted again.
I imagine this is three entries in the database file for future messages.
The end user's message never delivers and they freak out. I know the
answer
is to probably whitelist these domains but I didn't have the time to
keep up
with it.
Another issue that I ran across was even though I had set the greylist to
accept after 30 seconds the sending server would wait much longer to try
again (sometimes a half day or more).
Do you see this behavior on your side? I would love to turn the rule
back
on but it caused too many interruptions. YMMV though. Thanks!
