Sure, daily summary should be fine, but on a bad day these non-deliverable admin-emails will add up, and postfix keeps trying to deliver them. So my logs show quite a few failed delivery attempts. Queue of undeliverable mail grows. Neat-freak in me gets very jumpy.
Like I say elsewhere, slight mis-reporting on my part, it's my "smart-host" up-stream out-going smtp that is rejecting the mail w
spam-attachments.
The "smart host" doesn't seem very smart if it is rejecting spam mail with a 4xx (retryable) and not a 5xx (failure) status.
Another thought is just turn off admin_immed_notify, but of course that will also turn off notices for mail that might not be spam.
