I don't follow; why would using the FS to communicate that info >require moving the code into qmail-smtpd? My greylister uses (IP, from, to) to recognize a retry, and then whitelists the IP. The code that collects the from and to addresses is in qmail-smtpd. I suppose you could break it in half and put a shim in between or fork and run some other program to do the greylist check, but those both seem slow and clumsy compared to what I do with a UDP transaction. I have three smtp servers sharing the same greylist, all using UDP to talk to the same greylist server. R's, John |
