We don't want to accept mail and then later bounce (backscatter) it, so at a minimum, the outer servers need to be able to do recipient validation and spam scanning, and those services can have hiccups. No matter how far you push the problem down the road, there's a fundamental limit you hit eventually. > When it comes to spam and virus filtering, you could skip spam > filtering for "buffered" email, ergo email that was received during > outage.

Instead I'll just say that us silently deleting emails is not a very satisfying solution to the problem of someone else silently deleting emails. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
