Hi Michael, Seems I was to hasty. When trying openssl s_client -starttls smtp -connect <servername>:<port> There is something happening. But,
CONNECTED(00000003) depth=0 C = NL, L = Leiden, O = Ceelie, CN = mail.ceelie.info, emailAddress = elpa...@ceelie.info verify error:num=18:self signed certificate verify return:1 depth=0 C = NL, L = Leiden, O = Ceelie, CN = mail.ceelie.info, emailAddress = elpa...@ceelie.info verify return:1 --- Certificate chain 0 s:C = NL, L = Leiden, O = Ceelie, CN = mail.ceelie.info, emailAddress = elpa...@ceelie.info i:C = NL, L = Leiden, O = Ceelie, CN = mail.ceelie.info, emailAddress = elpa...@ceelie.info and --- SSL handshake has read 2438 bytes and written 464 bytes Verification error: self signed certificate --- New, TLSv1.3, Cipher is TLS_AES_256_GCM_SHA384 Server public key is 4096 bit Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated Early data was not sent Verify return code: 18 (self signed certificate) It seems to just hang on to the self-signed cert. How to remove this? Regards, Arie C2 VodafoneZiggo Internal
