Hi,
When accessing a managesieve server which provides broken TLS
connections, it is quite useful that sieve-manage-open-server() ignores
STARTTLS capability. Therefore, I propose the following patch.
Regards,

The patch looks fine and not likely to cause a trouble. I've
committed it in the Emacs master with this log entry:
sieve-manage.el: Allow user to avoid STARTTLS capability test (bug#24422)
* lisp/net/sieve-manage.el
(sieve-manage-ignore-broken-tls): New user option.
(sieve-manage-open-server):
Don't test STARTTLS capability if the option is set (bug#24422).
Thanks.

I think the option is badly named. It doesn't ignore broken TLS
(whatever that means), it avoids STARTTLS altogether. So maybe it should
be `sieve-manage-ignore-starttls' or something like that.

Agreed. I misunderstood what it tries to do. It is irrelevant
if the one is broken or not, it simply makes it not use STARTTLS,
and the docstring is correct:
"Ignore STARTTLS even if STARTTLS capability is provided."
I've renamed it as suggested, with this log entry:
sieve-manage.el: Rename sieve-manage-ignore-broken-tls
* lisp/net/sieve-manage.el (sieve-manage-ignore-starttls):
Rename from sieve-manage-ignore-broken-tls. If it is set,
sieve-manage will never use STARTTLS even if the server says
it is capable (but may be broken).
Thanks.

Thank you, as always!!! This can be marked as done?
