I'm sorry to keep nagging ;) After exploring the issue more, I am even more confused as how this is supposed to work, although I find it likely it's me doing something wrong.
I have tried googling, but haven't found anything useful. There are two things bothering me: 1) dbmail isn't sending the bounce message, 2) it gives back a temporary error to the MTA (it should be a "persistent transient" error, so permanent is better). In the code, there's only one place that is calling bounce() with BOUNCE_STORAGE_LIMIT_REACHED, and that is in sort_and_deliver(). There are two db_copymsg() calls in this function that can return -2, but only the first will send the bounce, and the other will only write a message in the log. Since bounce() is never called, but I see the log message, I conclude that the first one isn't triggered. In either case, it will return DSN_CLASS_TEMP. Unless my brain has taken vacation, it must be bad to return temporary errors to the MTA when the mailbox is full. Both dbmail-smtp and dbmail-lmtpd seems to only give back OK, temporary failure or permanent failure, so I cannot see a way to let the MTA handle it. Btw, I've got to ask, is there any dbmail documentation around I've missed? The only pieces I'v seen is the install document and the rather sparse man pages.
