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:

netstat -tanp | grep 419 tcp 0 0 0.0.0.0:4190 0.0.0.0:* LISTEN 693351/dovecot tcp6 0 0 :::4190 :::* LISTEN 693351/dovecot

from roundcube host to dovecot host:

90-sieve.conf:

plugin { sieve = file:~/sieve;active=~/.dovecot.sieve recipient_delimiter = + }

20-managesieve.conf:

protocols = $protocols sieve

service managesieve-login { inet_listener sieve { port = 4190 } }

protocol sieve { }

20-lmtp.conf:

protocol lmtp { mail_plugins = $mail_plugins sieve }

Postfix config:

Thanks for your help. -jeremy

Any pointers to get dovecot configured with sieve for Roundcube filters? Things I’ve found through search seem a bit all over the place. I’m using CentOS 8/Rocky Linux hosts.

Thanks

managesieve plugin for roundcube should be able to configure sieve scripts if you open sieve port on dovecot.

$config['managesieve_port'] = 4190;

$config['managesieve_host'] = 'ssl://mx1.la1.blah.com';

$config['managesieve_auth_type'] = null;

$config['managesieve_auth_cid'] = null;

$config['managesieve_auth_pw'] = null;

$config['managesieve_usetls'] = false;

$config['managesieve_conn_options'] = array( 'ssl' => array( 'verify_peer' => false, 'allow_self_signed' => true, ), );

Same error in the logs. I’m actually not seeing a separate log for sieve. Maybe I have to define a log location or something?

Try null, and PLAIN should be in quotes.

$config['managesieve_usetls'] = true;

I'd set this option to false, and control the connection type by use of ssl:// or tls:// prefix in managesieve_host. ssl + tls does not make sense.

$config['managesieve_debug'] = true;

Did you check logs/sieve.log?
