Just to clarify: If I understand it correctly, there are configuration options how to handle STARTTLS which mimecast customers can modify, e.g., maybe something like access map entries in sendmail: TLS_Srv:example.com VERIFY My server also receives a lot of mail from mimecast without problems (e.g., RedHat notifications). _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
