Hi again > Unless Orange is performing object and link scanning / safety checks making > the recipients seem alive (to euromsg at least Never seen this kind of behavior from Orange. Could be happening from one of their security vendors but on several hundreds of emails ? seems highly unlikely. On our end, for the last 4 hours I see around 1500 bounces from Orange, with soft and hard bounces alike. Most hard bounces are first time sendings, and the other ones do not show any recent activity.
I'd again advise to reach out to their postmaster team to ask them to check on this if they can.

(Even exclusive of aliveness, just not rejected last time but some rejected now.) Or not all but enough that after some number of unknown recipient rejects Orange's MTA shifts to bouncing everything (for a while). /mark _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
