I have to reject office files for a certain domain plus notifying the original recipient about the rejection too.

require ["fileinto","reject","body","enotify","variables"];

if allof (address :contains ["To","TO","Cc","CC"] "@example.org", body :content "application/msword" :contains "") { set "to" "${1}"; # :matches is used to get the value of the Subject header if header :matches "Subject" "*" { set "subject" "${1}"; } # :matches is used to get the value of the From header if header :matches "From" "*" { set "from" "${1}"; } notify :message "Rejected Office Datei ${from}: ${subject}" "${to}"; reject text: Aus Sicherheitsgründen nehmen wir keine Office Dateien mehr an. Bitte senden Sie uns ein PDF. . ; }

A manual sievec call gives not error and if I remove everything but the reject line it works.

Any ideas?

The set does not work in allof with an other condition, so I use now:

if address :contains ["To","TO","Cc","CC"] "@example.org" { set "to" "${1}"; }

...

# :matches is used to get the value of the Subject header if header :matches "Subject" "*" { set "subject" "${1}"; } # :matches is used to get the value of the From header if header :matches "From" "*" { set "from" "${1}"; } notify :message "Rejected Office Datei ${from}: ${subject}" "${to}";

The notify needs as argument "mailto:${to}".

...

reject text: Aus Sicherheitsgründen nehmen wir keine Office Dateien mehr an. Bitte senden Sie uns ein PDF. . ; }

A manual sievec call gives not error and if I remove everything but the reject line it works.

Any ideas?

I used the sieve-test binary to figure out why it was not working.

My full script for checking mime-types as well as extensions and also notifying the orginal recipient is now the following:

require [ "foreverypart", "mime", "fileinto","reject","body","enotify","variables"];

if address :contains ["To","TO","Cc","CC"] "@example.org" { # :matches is used to get value of to, subject and from if address :matches ["To","TO","Cc","CC"] "*" { set "to" "${1}"; } if header :matches "Subject" "*" { set "subject" "${1}"; } if header :matches "From" "*" { set "from" "${1}"; }

# reject based on mime-type if allof(body :content "application/msword" :contains "", body :content "application/msexcel" :contains "") { # send notification to original recipient notify :message "Rejected Office Datei von ${from}: ${subject}" "mailto:${to}"; # send rejection message to sender reject text: Aus Sicherheitsgründen nehmen wir keine Office Dateien mehr an. Bitte senden Sie uns ein PDF.

Ralf Becker EGroupware GmbH . ; stop; } # reject based on extension of attachment foreverypart { if header :mime :param "filename" :matches ["Content-Type", "Content-Disposition"] [".doc",".xsl"] { # send notification to original recipient notify :message "Rejected Dateierweiterung/Fileextension ${from}: ${subject}" "mailto:${to}"; # send rejection message to sender reject text: Aus Sicherheitsgründen nehmen wir kein Office Dateien mehr an. Bitte senden Sie uns ein PDF.

New subject: sieve issue after upgrad

i recently upgraded a server from dovecot 2.1 to 2.3 unfortunately sieve does not appear to be working. The user scripts have not changed, and neither has the dovecont config. using managesieve allows me to create new sieve files and setting one as default updates the link in ~/ to point to the correct file, but the .dovecot.svbin file is not changed (unless i run sievec /home/username/.dovecot.sieve ) I have tested an out of office script that was working on the old system, and a simple test script that flags the mail as $label1 as per an example. email arrives in users mailboxes but sieve scripts don't appear to be doing anything. below is the output of doveconf -n (hostname changed for security)

both scripts are below (server/domain changed for privacy) the current test script active (test.sieve) is

require ["envelope", "imap4flags"]; if envelope "from" "heather@myserver.net" { addflag "$label1"; }

the out of office script (outofoffice.sieve) which was working previously is

This tells me that the Sieve plugin did not save the message (there is no "sieve: " prefix). So, this is not a "keep" action. Saving the mail to INBOX directly like that only happens when Sieve is not involved to begin with (plugin disabled or no Sieve scripts found) or when Sieve bails out upon error.

Here, all Sieve involvement abruptly seems to stop, which is very very weird.

I'd expect this to end in some sort of error message. Is there a /var/log/dovecot.error or something like that? You can verify where things are logged using sudo doveadm log find.

Regards,

Stephan.

Here, all Sieve involvement abruptly seems to stop, which is very very weird.

I'd expect this to end in some sort of error message. Is there a /var/log/dovecot.error or something like that? You can verify where things are logged using sudo doveadm log find.

Stephan.

There are other mails with the same "invalid address `postmaster@' to other users. Is a postmaster address is required for sieve to work.? if so where should it go. is it the sieve_user_email declaration ? thanks.

Aha! So, you tripped over a 2.3.1 bug. The best way to work around this is by setting a proper explicit value for the global postmaster_address setting (https://wiki.dovecot.org/LDA). So, Pigeonhole does not define this setting; it is defined by Dovecot LDA/LMTP.

Stephan.

Brilliant. that fixed it. the scripts are running again, and my test, and out of office is working. So it is just that there is no default for that field, and the example comments need to be updated. (i just checked the 2.3.4 source and the example 15-lda.conf still implies a default, or has the behaviour been fixed in newer versions so it works?) I'll let the slackware build maintainer know so it can be added to the readme for 2.3.1 version.

many thanks everyone for your assistance. regards, Tim

Sieve: reject certain mime-types and notify recipient

Can you turn on mail_debug=yes and provide logs of delivery?

Can you turn on mail_debug=yes and provide logs of delivery?

Can you share the script too?
