[Dovecot] Problem with sieve scripts including sieve scripts
I have the following global cmusieve scripts defined in /etc/dovecot/sieve, which is owned by the user deliver is run (virtual) as defined in the lda session of dovecot.conf:
global-spam.script ======================================
require ["fileinto"]; # Move spam to spam folder if header :contains "X-Spam-Level" "********************" { fileinto "Spam"; # Stop here so that we do not reply on spam stop; } elsif header :contains "X-Spam-Flag" "Yes" { fileinto "Spam"; stop; }
global-default.script ====================================
require ["include"]; include :global "global-spam.script";
i.e. all the default script does is call the spam script. I have created the compiled versions using sievec, making sure they are still owned by virtual:
mail sieve # ls global-default.script global-spam.script global-vacation.script global-default.scriptc global-spam.scriptc global-vacation.scriptc mail sieve #
In the plugins session of dovecot.conf I have defined the path for global scripts (so I can do the include :global thingie) and the path for the default script (just in case user does not have a custom script in the mail directory):
plugin { sieve_global_dir = /etc/dovecot/sieve/ global_script_path = /etc/dovecot/sieve/global-default.script }
So I send me some certifiable spam from my collection of test spam. This is what I got from the log:

From what I gathered, mailscanner saw it was spam and tagged it. When the mail got back, postfix gave it to dovecot deliver, which then passed to cmusieve. Now, cmusieve saw user did not have a script defined,
Jul 22 14:49:02 mail deliver(raub@domain.com): cmusieve: /var/spool/vmail/domain.com/raub/.dovecot.sieve doesn't exist
So, it used the default script as it should,
Jul 22 14:49:02 mail deliver(raub@domain.com): cmusieve: Using sieve path: /etc/dovecot/sieve/global-default.script Jul 22 14:49:02 mail deliver(raub@domain.com): cmusieve: Executing script /etc/dovecot/sieve/global-default.scriptc
But, instead of calling the spam script, it simply delivered the spam mail to the inbox,
Jul 22 14:49:02 mail deliver(raub@domain.com): msgid=000d01ca078a$d13122a0$6400a8c0@chameleonsh: saved mail to INBOX
Why?

First of all, this script can be made simpler by using the anyof() Sieve command, avoiding the need to specify the spam delivery verdict multiple times.

Why? Good question. Are you sure that the tested headers above are truly present in the message under consideration (check your INBOX)? I know that MailScanner uses custom headers and the SpamAssassin ones are not always produced in addition by default. For debugging purposes, could you put these rules inside the user's personal script (the .dovecot.sieve) to check whether these work at all?
I must say, I've never used CMUSieve's include support before, so I couldn't tell you whether there are any known issues with this.

Actually that was a goof. What I meant was to discard the mail if it had too many stars (it sounds better than saying X-Spam-Level was too high ;). Shame on me!

I just found the issue: I typed "X-Spam-Flag" instead of "X-Spam-Status" as defined in the dovecot.conf. Oops! My typing skills are weak!
