[courier-users] Greylisting with Courier-MTA on Debian

2007-09-23 Thread Tim Lyth
Hi all, I've just signed up to this list. I know that this topic has been discussed before (I've searched the archives for "Greylisting"), but there's FAR too many posts for me to sift through to find the answer I'm after. I'm following the details on this website (http://www.georglutz.de/wiki

I would like to express my sincere thanks to Gordon for putting together and maintaining courier-pythonfilter. I use more than just the greylisting feature and it is a "must have" add-on. I don't know how Sam and Gordon feel about this, but it would be really nice to have it included in the m

1 week with greylisting. Two spam email have been persistent enough to get through the greylisting - SA scored one as 4.7 and let it through (required 5.0), the other was 28.7 and got caught. Without checking the log files to find out how many connection attempts and what not as I have in previ
