Use sieve Filter with Thunderbird

Hi,

today i tried to use the sieve add-on of Thunderbird. But when i start the add-on no connetion to the server is established. The server is listening to port 4190:

Blockquote

netstat -tulpn | grep 4190
tcp 0 0 0.0.0.0:4190 0.0.0.0:* LISTEN 24080/dovecot
tcp6 0 0 :::4190 :::* LISTEN 24080/dovecot

Blockquote

Telnet to 4190 is possible:

Blockquote

“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 index ihave duplicate mime foreverypart extracttext imapflags notify”
“NOTIFY” “mailto”
“SASL” “”
“STARTTLS”
“VERSION” “1.0”
OK “Dovecot ready.”
NO “Error in MANAGESIEVE command received by server.”

Blockquote

So it seems that the server ist responding to a port 4190 request but Thunderbird don’t find the server.

Where can i find some helpful log files?

Kind regards

Jochen
