Good morning.
I am using Dovecot as an IMAP proxy -- using IMAPC -- and the system is working great. Thank you for contributing such great software to the community!
I'm using Dovcot 2.3.5 and Pigeonhole 0.5.5.
My server is located behind a content-filtering firewall that will mark incoming messages by adding "[SPAM]" to the subject line. I'm trying to use Sieve to identify those messages and move them into the Spam folder. I have a basic Sieve script that looks like this:
require ["fileinto"];
if anyof (header :contains "Subject" "[SPAM]",
header :contains "X-Spam-Flag" "Yes"){
fileinto "Spam";
stop;}
I can see in the logs that Sieve is loaded, and also the imapsieve_plugin
Debug: sieve: Pigeonhole version 0.5.5 (2483b085) initializing
Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.5.5 (2483b085) loaded
Sieve detects outbound messages (from the log: Debug: imapsieve: mailbox INBOX.Sent: APPEND event) but nothing registers for inbound, and my spam_rule is never triggered. Any suggestions?
Here is the output from "Dovecot -n":
