Actually I do confirm that filter works by 'From:' or by 'To:' fields. I couldn't make it work by header though. Please advise what exactly I should do to make it work by 'Delivered-To' header (if possible at all).

So, you're actually confirming that 'filter by header' is working correctly, but that it is not sufficient as a measure against spam?

I believe you should direct your attention to configuring a spamfilter such as spamassassin or spamd on your mailserver and then train that spamfilter to become better at catching spam - this is not really something you want a mailclient to handle.

Hi all, How do I create filter by header? I installed filters plugin and I can see

$config['spam_headers'] = array('X-Spam-Flag','X-Spam-Status','X-Yandex-Spam');

line in my configuration file

/var/www/html/example.com/roundcube/plugins/filters/config.inc.php

I don't have any of these headers like X-Spam-Flag, X-Spam-Status, X-Yandex-Spam. But I have Delivered-To header that shows my username1@gmail.com So I tried to add ,'Delivered-To' into config line, then created filter

If the field [Delivered-To] contains gmail move the message to Inbox.gmail from Inbox (Messages: All, Mark: As read)

But it didn't work for me. The problem is that some smart spammers do not include my email address into To: or Cc: field, so I can't filter it (those that include it go to needed folder indeed).
