Package: courier-mlm Version: 0.73.1-1.6 Severity: normal Dear Maintainer,
I've encountered some bugs in couriermlm, when a list is setup the option 'NOBOZOS=1' is set by default, which should bounce bad ctl command messages sent to user-list@domain instead of user-list-command@domain. What's supposed to be happening is that messages like: cat <<EOF To: user-list@domain Subject: list manager, do this help EOF bounce, because they should be sent to: user-list-help@domain in order to work correctly. Basically any message starting with a keyword like help. subscribe, or unsubscribe (perhaps a few others) is supposed to bounce. However, the actually filtering is way too aggressive. Any message where any line begins with a keyword, wil bounce. e.g: cat <<EOF To: user-list@domain Subject: leftover pizza Hi guys, There's some pizza leftover in the kitchen. Help yourselves! -Me EOF will bounce. You won't bounce a message like this, though: cat <<EOF To: user-list@domain Subject: leftover pizza Hi guys, There's some pizza leftover in the kitchen. So help yourselves! -Me EOF because that line no longer *starts* with the keyword 'help'. This behaviour, I would argue, is even worse than not informing people the they haven't formatted their subscribe / unsubscribe messages properly, which the list admin should recognize immediatly. In the 'NOBOZOS=1' case you bounce perfectly good mail for no immediatly obvious reason. The behavior should either be corrected, or the default should be 'NOBOZOS=0'.
