Requested feature: better error handling in email replies

I just installed redmine on kabissa, which includes round-trip email functionality for reporting bugs and discussing them all through email. One feature I like better about redmine that I would like to have on og_mailinglist is better error handling in email replies. redmine errors come back as standard mailer-daemon bounce messages, as in the example below. Not only is the error reasonably meaningful, but it includes a full copy of the email that generated the error. This makes it possible to troubleshoot what is going on.

Meanwhile, og_mailinglist sends errors that are cryptic and have no mention at all of the original message making it unnecessarily hard to figure out what is going on.. esp if the user sent several messages.

The redmine install instructions for email are at http://www.redmine.org/projects/redmine/wiki/RedmineReceivingEmails

Cheers,

Tobias

Hi. This is the qmail-send program at foo.org.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

:
Request was denied by your Redmine server. Possible reasons: email is sent from an invalid email address or is missing some information.
