Hi,

non-existing rua= addresses generate loops, because the target domain sends a bounce, and on the next day the generator sends them a report for that one message. The report bounces, and so forth...

Three ways to prevent that:

1, accurately store all bouncing addresses so as to avoid sending again,

2, omit aggregating data for DSNs, or

3, omit sending reports that have only one row.


I'd opt for 2. However, the ID says "The report may include [...] The counts of messages based on all messages received". Would it make sense to change that so as to exclude DSNs?


Best
Ale
