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.

IPv6/TCP

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.
