I was trying to set up the "new" antispam plugin with the mailtrain backend, and i was trying to use the sendmail binary that's part of a qmail system. The message wouldn't get sent and i kept getting exit error 100 from the /var/qmail/bin/sendmail binary. To try to figure out what was happening, i mean a fake sendmail program, which is nothing more than a bash script to capture the command call input. The script is rather simple, it just places the calling parameters into a txt file and the stdin into another. So i tried a retrain and went to see what those txt files had. The parms.txt file was fine apparently, with cat /tmp/sendmail-parms.txt i got Then i did the same to the message file, with cat /tmp/sendmail-msg.txt, and i got the follwing Received: from femme-fatal.resnet.costabasto.com (HELO femme-fatal) (192.168.0.20) As you can see, there is no new line in the first line. Return-Path and Delivered-To are set in a single line, which makes qmail-inject (which is later used by /var/qmail/bin/sendmail) to abort like this cat /tmp/sendmail-msg.txt | /var/qmail/bin/sendmail -f [EMAIL PROTECTED] [EMAIL PROTECTED] Before i go into digging the plugin code i was wondering if i'm not seing things clearly and thinking this is in fact a bug in the plugin code.
