Charles, It's been a long time since I've worked in that code, but here are some quick thoughts:
1) There's already code reading the headers, searching for mail loops by looking at the Delivered-To header. You could tap into that code. 2) You could look at simscan.c to see how they're interfacing with spamc. -Tom On Aug 25, 2014, at 5:48 PM, Charles Sprickman wrote: > Off to try to follow vdelivermail.c… :) !DSPAM:53fc20e356441762611622!
