For clarity: I did not look at any DNS records before making that statement, it was my short-form explanation of what the error message means in practice. 95+% of the time, it means "they have DNS servers which don't reply when asked for TLSA records". To get more details out of Exim, run with `-d+transport+dns` to get debugging, enabling additional debug content in the "transport" and "dns" areas. -Phil -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
