In fact, does this plugin work for anyone at all? I set everything to the vanilla download and it didn't work at all. It didn't test positive for on:
if (strpos($message->subject, $this->spam_text) === 0)
even when I used the as-shipped spam string "***SPAM***". When I changed the === to >= I got the error
[22-Mar-2015 11:27:41 America/New_York] PHP Fatal error: Call to undefined method rcube_imap::messagecount() in /user/util/src/roundcubemail-1.0.4/plugins/movespam/movespam.php on line 51
browsing on this forum suggested changing messagecount() to count(), which I did. At that point it once again moved ALL messages from inbox to junk, regardless of whether "***SPAM***" was in the subject line or not.
I don't think this plugin is ready for prime time yet.
Has anyone gotten it to work successfully? If so, how?
