I've recently started seeing these error messages when sending to yahoo 2014-01-15 10:49:55 1W3O2j-0002iY-Mv TLS error on connection to mta5.am0.yahoodns.net [98.138.112.34] (gnutls_handshake): The Diffie-Hellman prime sent by the server is not acceptable (not long enough) 2014-01-15 10:49:55 1W3O2j-0002iY-Mv TLS session failure: delivering unencrypted to mta5.am0.yahoodns.net [98.138.112.34] (not in hosts_require_tls)
After some googling I thought maybe my self signed TLS key was not strong enough and so regenerated it with - openssl req -x509 -newkey rsa:2048 -keyout /etc/exim4/eximcert -out /etc/exim4/eximcert -days 9999 -nodes but I still get the same error message. Am I on the right track or is there something else I need to do in order to get yahoo to accept the TLS session? thanks -- ## 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/
