Hi everybody,
I have a Postfix smarthost and a Postfix client who shall send mails
through that smathost using a TLS-certificate.
I don't get the client to send the certificate to the smarhost though.
The error is:
Anonymous TLS connection established from client.example.com [...]
smarthost: http://paste.debian.net/770746/
client: http://paste.debian.net/770757/
When using openssl s_client to test the authentication I get:
Trusted TLS connection established from client.example.com [...]
Like this I know that my client certifikate and the verfication on the
smarthost ist generally working.
http://paste.debian.net/770599/
When using openssl I can see "read certificate verify" in the traffic.
When sniffing the Trafic I can also verify that with openssl the client
is issuing "Certificate Verify"
http://paste.debian.net/770668/
But when the postfix client authenticates it does not send the certificate.
http://paste.debian.net/770667/
The openssl command is:
sudo openssl s_client -starttls smtp -cert
/etc/ssl/certs/client_example_com.crt -key
/etc/ssl/private/client_example_com.key -connect 192.168.59.3:587
What am I missing?
Something that makes me wonder as well ist, that even the file
/etc/postfix/relay_clientcerts is epmty I get a trusted connection with
the openssl command.
Warm regards,
Tom
