This statement matches what I experienced. Freshly installed mail servers (with matching SPF entries) were unable to send email to T-Online until I contacted the e-mail address listed in the rejection message and asked for unblocking. That never took longer than two business days. -Ralph _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
