if i have an EC mail server cert and if an MTA setup to send/receive gives the following:
$ openssl s_client -cipher ECDH -starttls smtp -connect medusa.blackops.org:25 CONNECTED(00000003) 139821090178704:error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure:s23_clnt.c:762: does that mean it cannot connect *to* me because it doesn't have any EC ciphers (openssl from 0.9.8 to 1.0.0 i believe?) which are required because of an EC ssl cert ? why doesn't mail then get delivered in the clear ? i can receive mail for example from gmail which connects to me with an ECDSA cipher suite i posted postconf -n in previous question example postfix/smtpd[7060]: initializing the server-side TLS engine postfix/smtpd[7060]: connect from medusa.blackops.org[208.69.40.157] postfix/smtpd[7060]: warning: milter inet:127.0.0.1:10023: can't read SMFIC_OPTNEG reply packet header: Connection timed out postfix/smtpd[7060]: warning: milter inet:127.0.0.1:10023: read error in initial handshake postfix/smtpd[7060]: setting up TLS connection from medusa.blackops.org[208.69.40.157] postfix/smtpd[7060]: medusa.blackops.org[208.69.40.157]: TLS cipher list "!ANULL:!EXPORT:!MD5:!DES:!LOW:ALL:@STRENGTH" postfix/smtpd[7060]: SSL_accept:before/accept initialization postfix/smtpd[7060]: SSL3 alert write:fatal:handshake failure postfix/smtpd[7060]: SSL_accept:error in SSLv3 read client hello C postfix/smtpd[7060]: SSL_accept:error in SSLv3 read client hello C postfix/smtpd[7060]: SSL_accept error from medusa.blackops.org[208.69.40.157]: -1 postfix/smtpd[7060]: warning: TLS library problem: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher:s3_srvr.c:1358: postfix/smtpd[7060]: lost connection after STARTTLS from medusa.blackops.org[208.69.40.157] postfix/smtpd[7060]: disconnect from medusa.blackops.org[208.69.40.157]
