Sieve now seems to require tls:// prefix on hostname

[chongma]

Sieve wouldn't connect and had php error: this server doesn't support any authentication methods.
When debugging the "SASL" was empty ""

usetls was set
$config['managesieve_usetls'] = true;

Appending tls:// to the domain fixed it
$config['managesieve_host'] = 'tls://domain.tld';

It also wasn't respecting the managesieve.inc.php that was copied into the config. I had to edit directly in plugins/managesieve/config.inc/php which means the config will be overwritten

Would be nice to have a good readme on managesieve

I just fixed my setup adding the 'tls://' prefix as you mentioned, but using 1.6.2 it worked putting that into the external config file.
