This is not an error. It is just informational. You don't trust any CAs, so no certificates are verified. If I recall correctly, sufficiently recent versions of Postfix (I believe 2.9 or later) don't log this message when TLS is opportunistic and the smtp_tls_loglevel is 1 or less (the recommended log level is 1). If you find this log message annoying, upgrade to Postfix 2.9.7 or 2.10.2. When remote certificate authenticity is not enforced, there is no point complaining about it. -- Viktor.
