Can confirm this. It's a blocker. Matter of fact, while trying to establish a TLS connection using the usual `openssl s_client -showcerts -connect example.com:4190` works beautifully, ksieve doesn't even try to negotiate a TLS connect. It's just TCP's SYN; SYN, ACK; ACK; at this point the TCP connection is established, and it would be the client's job to initiate a TLS session – never happens, there's 0 bytes exchanged, until at some point either I close the program or the server drops the idle conneciton. Functionality of the same server has been verified through an unenencrypted direct connection. Attaching Wireshark capture. Created attachment 150778 [details]
Wireshark capture of the very data-less conversation with a TLS server over IPv6/TCP
Tested version of libksieve was 21.12.2, by the way, can't map that to the versions offered as choice above. Having a hard time building git master from source. Also reproducible under 5.20.3 (22.04.3) |
