I notice in my Smartlist log following error: ------------------ Tue Nov 28 10:03:55 CST 2006 procmail: Program failure (67) of " formail -rtzc -xTo: >tmp.from" To: <angenmap-request@animalgenome.org> Subject: Delivery Status -------------- (it should record but "From: " line is missing) I checked and this recipe is only in "rc.request" and "rc.submit". File permissions on related files are: -rw-rw---- 1 smlst smlst 577 Dec 2 09:31 tmp.from -rw-rw---- 1 smlst smlst 7571 Dec 2 08:36 tmp.mail -rw-rw---- 1 smlst smlst 9816 Dec 2 09:31 tmp.request The occurances of this error are almost all from mail daemon bounces (only a small portion of all mail daemon mails). Other than this the smartlist is working fine. I googled but don't find much on this (what's the code "67" for?) Zhiliang
