After installing Postgrey last night, and verifying it actually works, I set the delay-option to 60 seconds. But then I found it delays my messages for too long.
In my headers, I see entries like:
X-Greylist: delayed 1025 seconds by postgrey-1.24 (...blah blah)
Another test gave me a 1101 second delay.
Does anyone have an idea what could be the problem?
