I just noticed that in 'rejected entries' that greylisting is blocking a few gmail addresses trying to email my account. Looking at the source IP they are indeed coming from gmail servers. This clearly is not good. I think the timeouts need expanded or something. Untill then I have turned greylisting off. I think its an excellent idea but the minimum of 30 minutes of wait and timeout of 4 hours is just too narrow. It should be 10 minutes to like 12 hours in my opinion. Perhaps even just 5 minutes. Even 5 minutes will give new spam sources time to hit a few spam traps and get listed so blacklist and/or spamassassin can catch them.

Since mail servers typically retry every 15 minutes would it not be better to delay only say 10 -14 minutes instead of 30? In 10 minutes due to spam traps etc. a sender is likely been reported to many blacklists and possibly razor. This would be less delay to wait also. I have sent several emails from my email address at work over last couple days. They have never gotten through yet. Its running on Exim with Clamav and spamassassin. I am not sure why but I suspect its not retrying every 15 minutes like its supposed to by looking at the log files. In exim.conf it looks to be setup to try every 15 minutes though. I suspect maybe a high load due to spamassissin is delaying processing the queue and the large amount of messages in the queue. Perhaps the windows can be extended from 4 hours to 12 hours to fix things like this?
