It was the CRLF sequence from creating the file on a Windows machine. I haven't had a problem with this in a long time, bash scripts etc. work fine, no matter if LF or CRLF is used, but it seems to make a difference when including a file. > > BTW: Postgrey recommend a maximum delay of 300. Is there a reason > you're using 660? It's the default and been the default since postgrey saw the light of day, but I wouldn't deem it "recommended". ;-) I've been doing greylisting (with sendmail) for many years and started out with ten minutes. This has proven to be quite successful, but there is a growing number of spammers that come back after exactly ten minutes, so I'm moving it up to 11 minutes on new machines. I doubt that 5 minutes gives any advantage in terms of faster turnaround time for ham messages. Most MTAs retry after 15 or 30 minutes, I would actually consider an MTA that retries after only 5 minutes a bit rude.
