I'm giving up on procmail. It is poorly supported and appears to only work for local delivery (user mailbox must exist on the box) as far as I can tell. I am using SA as an email gateway, and I just don't think procmail works that way from the little I can find on the subject. Procmail doesn't even create a log file for me. So, I am now looking at maybe using amavisd-new or mailscanner, as much as I hate stacking somewhat redundant apps on top of each other. More stuff to break...
How about turning on logging in procmail and examining the logs? Best Martin -- http://www.tm.oneiros.de
