Hi Here is Marco from ESP Contactlab. t-online.hu is blocking our emails. It's small traffic, but it's very problematic because there are transactional messages too.
Is anybody in the list from t-online.hu who might help? I've tried abuse@ and postmaster@ but had no responses. Kind regards Marco Franceschetti Head of Deliverability | ContactLab marco.francesche...@contactlab.com Via Natale Battaglia, 12 | Milano contactlab.com/it _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
