Nice. Finally got around to switching. Had to add filter to my dspam pipe (another one I'm overdue for replacing) . Antispam plugin seems to have automatically converted line endings from "mail-type" '\r\n' into linux plain '\n' . Like so: sed -e 's/\r$//' | dspam ...

I wonder if the method shown in https://wiki.dovecot.org/HowTo/AntispamWithSieve will cause incoming mail (via LMTP) that is already flagged as spam to be processed by report-spam.sieve and, in consequence, will be learned as spam for a second time, which would of course be undesirable? -Ralph

Check out https://wiki.dovecot.org/Pigeonhole/Sieve/Plugins/IMAPSieve, which explains that sieve is normally only used at delivery time, but the sieve_imapsieve plugin runs a *different* sieve script based on IMAP actions (for example, COPY). So, when you deliver, your main script tells dovecot WHERE to deliver to. When you issue and IMAP COPY command, the Antispam scripts tell dovecot to pipe the message to spamassassin. The delivery does not involve IMAP and the IMAP COPY does not constitute redelivery. -- For more information, please reread.

Dspam direct pipe needs mail-line-endings (\r\n) translated into unix line-endings (\r). like so: ----- learn-spam.sh --------- #!/bin/sh sed -e 's/\r$//' | /usr/bin/dspam --source=error --class=spam ----- learn-ham.sh ---------- #!/bin/sh sed -e 's/\r$//' | /usr/bin/dspam --source=error --class=innocent ------ Theese will be invoked with the owner of the mailbox as current uid, so that is all.
Glad I poked around on the list today! Thanks to all for the suggestions about integration with dspam. I'll definitely have to look into this, as I rely on moving messages to a specific folder with various IMAP clients to retrain dspam false positives and negatives. A quick pair of questions: * Does Dovecot support the IMAP "MOVE" command at this time? * If so, what is the syntax for "COPY or MOVE" for the _causes variables? I did see messages from 2011 discussing it, but nothing since. While the script looks like it could be modified for use with dspam (with the great suggestions from others on the list), it has the same problem as "antispam" with bulk moves being serialized and tying of the client until they complete. I'll probably have to break down and look into using FreeBSD's auditd to trigger the actions and then de-queue the successfully processed messages. Sieve doesn't look like it can handle asynchronous processing, but I'd certainly be interested if I'm missing something there. One less thing to configure and maintain!

Greetings to the list :)
I've been meaning to ask a couple of questions about the imapsieve for
antispam.
Firstly, I guess that the example at the bottom of the page
"https://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/IMAPSieve" is
meant
to link to the new example at
"https://wiki2.dovecot.org/HowTo/AntispamWithSieve" now?
Also... in "imapsieve_mailboxX_name = ${directory}" is the string a
literal, or is it working with the 'special use' flagged directories
from the xx-mailboxes.conf? I'm asking as though I only have a few users
to worry about, different mail clients each have their favourite special
folders. IE thunderbird uses "junk" but one Outlook express version
likes "Junk E-mail" and I have a different favourite from another
version of OE too. So in mailboxes.conf I just added extra special use
lines which seemed to make things happy. Otherwise I ended up with the
server configured 'spam' folder showing as basic folder, and then each
client adding it's own chosen spamfolder each time too.
But, if the imapsieve is only matching to literal foldernames, should I
just duplicate the trigger lines for each type of junk folder or is
there a method to have the sieve script enumerate all the options listed
by 'special use' or is there a better method for this? I want to put
the spam-mail-filing script as a global sieve script as all users will
need it, rather than duplicating out for each user.
Many thanks ,
Andy R
