Here’s some more information:
When attemtping to load the filters configuration on Roundcube, I see this in Dovecot’s logs:
Jun 06 23:25:30 mx1.la1.blah.com dovecot[693354]: managesieve-login: Disconnected: Too many invalid commands. (no auth attempts in 0 secs): user=<>, rip=192.168.30.48, lip=192.168.30.21, session=<5628p9Xg6oTAqB4w>
I don’t know if user=<> indicates that the username isn’t being passed properly but it seems like a good guess based on "no auth attempts in 0 secs”.
My Roundcube configuration looks like this:
$config['managesieve_port'] = 4190;
$config['managesieve_host'] = 'ssl://mx1.la1.blah.com';
$config['managesieve_auth_type'] = PLAIN;
$config['managesieve_auth_cid'] = null;
$config['managesieve_auth_pw'] = null;
$config['managesieve_usetls'] = true;
$config['managesieve_conn_options'] = array(
'ssl' => array(
'verify_peer' => false,
'allow_self_signed' => true,
),
);
$config['managesieve_conn_options'] = null;
$config['managesieve_default'] = '/etc/dovecot/sieve/global';
$config['managesieve_script_name'] = 'managesieve';
$config['managesieve_mbox_encoding'] = 'UTF-8';
$config['managesieve_replace_delimiter'] = '';
$config['managesieve_disabled_extensions'] = [];
$config['managesieve_debug'] = true;
$config['managesieve_kolab_master'] = false;
$config['managesieve_filename_extension'] = '.sieve';
$config['managesieve_filename_exceptions'] = [];
$config['managesieve_domains'] = [];
$config['managesieve_default_headers'] = ['Subject', 'From', 'To'];
$config['managesieve_vacation'] = 0;
$config['managesieve_forward'] = 0;
$config['managesieve_vacation_interval'] = 0;
$config['managesieve_vacation_addresses_init'] = false;
$config['managesieve_vacation_from_init'] = false;
$config['managesieve_notify_methods'] = ['mailto'];
$config['managesieve_raw_editor'] = true;
$config['managesieve_disabled_actions'] = [];
$config['managesieve_allowed_hosts'] = null;
My dovecot configuration looks like this:

Thanks for your help.
