Thanks for the hint. 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.
Glad to hear :-)
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.
You're history with greylisting eclipses my recent foray into the field, so I bow to your experience. I took the 300 from the CentOS HowTo where they write:- <quote>Setting your delay to values larger than 300 Seconds ( 5 Minutes ) is really not recommended.</quote>
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.
I started my delay at 60 seconds as the how-to suggests, and have moved it up to 300 now. If your experience suggests 660, then I'll try that next ;-)
Anything to kill Spam is cool in my book 8-)
