Unless Orange is performing object and link scanning / safety checks making the recipients seem alive (to euromsg at least), but later the accounts are disabled or closed for whatever reasons. (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
