If I'm reading the logs correctly, it would appear Postgrey is delaying mail longer than in the config file: file: /etc/default/postgrey contains a line: Code: POSTGREY_OPTS="--inet=60000 --delay=460 --max-age=30" After the edit restarted both postgrey and postfix. selction of Mail log entry: Code: postgrey[2734]: action=greylist, reason=early-retry (3176s missing) Am I correct in assuming postgrey is waiting for 3176 seconds until it will allow this email through? If so, I'm at a loss as to why the --delay=460 isn't being honoured? The POSTGREY_TEXT entry is being used properly.
