There is generally more information in the log than this when the TLS handshake fails. DO NOT over-summarize the logs. > (ever from yahoo servers) > i can't figure out wher my mistake come from. Record a full packet PCAP file containing a session from a Yahoo host. Filter this capture file to contain full packets from exactly one TCP session. Run that through wireshark, see where in the TLS handshake the problem starts. Make the full capture available (post a URL, ...). > here is my postconf -n : http://paste.debian.net/39693/ > postfix version is : 2.9.6-2 (debian stable package) > > can please somebody give me some help (i fear loosing some emails > from yahoo) TLS to your domain looks good when I test. Your server certificate is self-signed, but that's hardly unique to you. The expiration date on the self-signed cert could arguably give some systems indigestion, perhaps a 2-10 year lifetime is more reasonable than 1000 years.
