It looks like the code, by default, sends the message to “noreply@” followed by the domain, with all the intended recipients in the BCC field. I end up getting 3-6 bounces per message due to the “delayed” notifications. It thought it would go away after someone (else) had subscribed to the topic, but that is simply not the case.
The code needs to be only slightly more sophisticated:
1.) it should NOT send an email if there are no recipients (because… logic)
2.) the “from” address should be “noreply@<domain>” or otherwise configurable
I’ll see if I can work up a patch if I’ve got sufficient free time (unlikely, but I’ll try). Anybody know the who/how/where of it?
