I have a rc.local.00 recipe modified from Rob Lingelbach <rob@alegria.com> to catch multipart/html/coded/... mails which has been working well for quite a while. Recently I noticed some mails sneaked through my list. I checked everything and could not find a clue. I attach the log error and a sample of the rc below and hope some of you could spot some syntex error that is obvious to you but not to me ;-) Thanks in advance! Zhiliang PS: Due to the mail editor the copied lines were forced some extra line breaks -- in my recipe I do have proper line breaks/continuations ("\") -------- log -------- procmail: Error while writing to " formail -r -i "From: $listreq" -A"X-Loop: $listaddr" | \ (/usr/bin/cat; /usr/bin/cat info/reject.attach $tmprequest) | \ $SENDMAIL -t " --------------------- rc.local.s00 (sample) --------------------- # Modified from Rob Lingelbach rob@alegria.com tmprequest=tmp_request :0 c | /usr/bin/cat > $tmprequest :0 BH * ^This is a multi-part message* { :0 c | formail -i "Listmaster: <--Intercepted for multi contents-->"| \ $SENDMAIL -oi $maintainer :0 | formail -r -i "From: $listreq" -A"X-Loop: $listaddr" | \ (/usr/bin/cat; /usr/bin/cat info/reject.attach $tmprequest)|\ $SENDMAIL -t } :0 BH * ^Content-Type:.*(multipart|enriched|coded|mixed) { :0 c | formail -i "Listmaster: <--Intercepted for enriched content-->"| \ $SENDMAIL -oi $maintainer :0 | formail -r -i "From: $listreq" -A"X-Loop: $listaddr" \ -i "Listmaster: <--Intercepted for Enriched content-->" | \ (/usr/bin/cat; /usr/bin/cat info/reject.attach $tmprequest) | \ $SENDMAIL -t }
