Sieve does not work after upgrade to 12.0.18 and installing dovecot

[Eser]

Hi,

i use Plesk on a vserver which was offering it in version 11.x, i upgraded to 12.0.18, then i installed Dovecote on the panel. Everything went fine. Mailserver is working.
BUT sieve does not allow me to login and create filters.

I tried telnet against 4190, and it works:

-------------------------------------------------------
Connected to mail.xxxxxxxx.xxx.
Escape character is '^]'.
"IMPLEMENTATION" "Dovecot Pigeonhole"
"SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave imapflags notify"
"NOTIFY" "mailto"
"SASL" "PLAIN LOGIN DIGEST-MD5 CRAM-MD5"
"STARTTLS"
"VERSION" "1.0"
OK "Dovecot ready."
-----------------------------------------------------

But when i use my sieve plugin for thunderbird OR access plesk's webmailclient Roundcube opening the filter module, it doesnt work. On Thunderbird i see the loading animation, thats it. On Roundcube it says "Unable to connect to sieve server".

Looks like something is missing. I can definitely access 4190 on my server from anywhere. So no firewall issue. I didnt change anything on configs, since plesk is handling it.

Roundcube log doesnt give me anything. I dont even see logs added (to syslog or mail.*) while i try to connect.

Whats wrong here?

I believe this issue is known to us – please see if KB - http://kb.odin.com/en/121429 solves it for you.

Thanks for the reply, but i know that article. Doesn't help at all, so i very hope sieve is going to work soon. I don't even know why its not working, i don't see logs being created, looks like a firewall problem, but i can connect to sieve. It might be related to TLS/SSL. But i'm not sure.

Hi Eser,

maybe this works for you as a solution?

Nope. Still no way to connect.

At least im able to setup the sieve script manually on my mailbox so my mails are filtered, but no way to manage that sieve script via Roundcube or Thunderbird sieve plugin.
