FYI: Got a temporary a problem with mail to lists.cluenet.de: ----- Transcript of session follows ----- <[email protected]>... Deferred: 403 4.7.0 TLS handshake failed. Warning: message still undelivered after 4 hours Will keep trying until message is 5 days old
Caused by: bjorn@canardo:~$ openssl s_client -6 -connect mail1.cluenet.de:25 -servername mail1.cluenet.de -starttls smtp -quiet 139725204116608:error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol:../ssl/statem/statem_lib.c:1929: WTF? I expected "dh key too small" which has been a bit of an issue since I updated openssl. But "unsupported protocol"? That's not good. But it's confirmed by e.g. https://ssl-tools.net/mailservers/lists.cluenet.de This must be embarrassing? Time to drop the "clue".... Bjørn
