alt Hacker NewsI also don't see why the DMARC reporting would retry sending. If the receiver isn't receiving right away, surely it's okay to just drop that report to keep the queue small.

We already had 'low effort' mail queues (for things like password reset emails: these are retried 1/2/4/8 minutes apart and don't generate bounces, other than an API flag and a metrics record), to which we added 'least effort' for DMARC reports. Retry once, then forget about the entire thing other than incrementing a counter for the destination domain.
