Hi list.

I use courier mostly with useraccount-based delivery (authpam) and let my 
users control which addresses exist and which don't. They can do this by 
providing suitable .courier-files.

A problem is, that if accidentially a user prohibits user "mail" from 
accessing his homedir (chmod 700 ~), courier accepts all mail to user-foobar 
and decides later in the delivery process if it is deliverable or not.

Is thare any option to tell esmtpd that unaccessible home dirs should be a 
showstopper for that user? 
If this occures, I want the user not to get any mail at all, it should be 
rejected with a temporary error. I run a cron job to fix the issue, but at 
the moment, this is kind of a race condition.

As far as I read the docs, there seems not to be an option for this behaviour. 
what do you think of such an option, could this be implemented?

Background:
If this situation occures, courier behaves much like QMail, accepting all shit 
and then bouncing it back to whereever Return-Path points to. This makes my 
box a spam-machine (I think of silly bounces as spam) and I got listed at 
spamcop for such reasons in the past.

So I want to prevent QMail-style mass-bouncing globally, what I think is not 
possible at the moment.

cu, Bernd
