Description
When connecting to IRC or XMPP servers the certificate validation always fails even when importing their CA and the certificate itself into Mono's certificate storage using the certmgr utility:
openssl x509 -in /etc/ssl/certs/Equifax_Secure_CA.pem -out Equifax_Secure_CA.crt -outform der certmgr -add -c CA Equifax_Secure_CA.crt

Here some useful SSL debugging commands:
gnutls-cli -V irc.oftc.net --port 6697 --crlf --x509cafile /etc/ssl/certs/ca-certificates.crt
openssl s_client -showcerts -host irc.oftc.net -port 6697 -CApath /etc/ssl/certs

Firstly, one should use -c Trust instead of -c CA. The former is what `mozroots` does. Not sure why but it works.
Secondly, it seems that there is something wrong with how smuxi uses the SSL library. A basic simple program works:
using System;
using System.Net.Sockets;
using System.Net.Security;
public class TlsTest {
public static void Main (string[] args)
{
Console.WriteLine("checking " + args[0]);
var tcpClient = new TcpClient (args[0], int.Parse(args[1]));
var ssl = new SslStream (tcpClient.GetStream ());
ssl.AuthenticateAsClient (args[0]);
Console.WriteLine("success");
}
}

Your tests deliver important information. I agree that the current situation seems to be that Smuxi is doing something that breaks the default cert validation for some reason. I will look into that.

Updated by Mirco Bauer 3746 days ago
First conclusion: certmgr --ssl is useless to populate the user store because it always imports into the CA user store instead of Trust user store! (see amended first conclusion)

Turns out irc.freenode.net sends the intermediate CA cert but not the root CA cert! See:
openssl s_client -connect irc.freenode.net:6697
First (amended) conclusion: certmgr --ssl imports the intermediate CA cert correctly in the CA store, as Trust is only for Root CA certs

Second conclusion: certificate validation in Mono works if the intermediate CA was imported and the root CA but not when just the root CA was added to the user Trust store.
Updated by Mirco Bauer 3746 days ago
Third conclusion: Smuxi can connect to irc.freenode.net with certificate validation enabled if the root CA was imported into the user Trust store and the intermediate CA was imported into the user CA store. This is probably a Mono bug.

Certificates stored in Mono's user cert store can be checked like this:
openssl x509 -inform der -in ~/.config/.mono/certs/CA/ski-B6A8FFA2A82FD0A6CD4BB168F3E7501031A77921.cer -text -noout

Fourth conclusion: Mono's default certificate validator is different than != SslPolicyErrors.None as a connect without a validation callback (return sslPolicyErrors == SslPolicyErrors.None) works but providing that minimal wrapper does not!

As a short term workaround, you can connect to SSL/TLS enabled servers using stunnel: https://smuxi.im/faq/usage/stunnel/
stunnel acts as a socket proxy between Smuxi and the IRCd and does the SSL/TLS handling. Smuxi connects to stunnel using a plaintext socket on localhost which talks to stunnel which talks to the IRC server using SSL/TLS
