Are bounce messages inserted into the queue via qmail-queue, or are they added some other way? If qmail-queue is used, and the QMAILQUEUE patch is installed, does the bounce process use the qmail-queue program specified by QMAILQUEUE, or is it hardcoded to use qmail-queue?
My reason for asking:
I am using a qmail-queue replacement to sign outbound messages with DKIM. Most of the outbound mail from my server is either from ezmlm, or from mail clients submitting through SMTP. I am successfully signing those messages by using QMAILQUEUE in the ezmlm .qmail files and the smptd script. But bounce messages are not being signed, and I would like to sign them. (Actually, I would prefer not to send bounce messages at all, but the ezmlm architecture uses bounces to send error messages).
I have tried setting the QMAILQUEUE environment variable in the qmail/rc script that starts qmail, but apparently either that is not getting passed to whatever process generates bounces, or it is being ignored. If possible, I would like bounces to be processed through a replacement program that signs them and passes them to the "real" qmail-queue, just like all other outbound messages.
I know I have a couple of other alternatives if I can't make this work. One alternative would be to sign the messages in a qmail-remote wrapper instead of qmail-queue. But since I've gotten the qmail-queue signing process working, I'm reluctant to re-engineer the process. Another possibility would be to rename qmail-queue to something else, and replace qmail-queue with the signing program which would then call the actual qmail-queue via its new name. But that will only work if the bounce messages are being sent through qmail-queue with the program name hard-coded.
