[Dovecot] SquirrelMail IMAP protocol errors?

Wed Apr 27 20:53:47 EEST 2005

I use Squirrelmail to filter messages, and it's doing this:

raw log in:

A009 UID SEARCH CHARSET ISO-8859-1 ALL Header X-Spam-Level {4}
****

A010 LIST "" "spam"

raw log out:

* SEARCH
A009 OK Search completed.
* BAD Error in IMAP command : Unknown command.
* LIST (\NoInferiors \Marked) "/" "spam"
A010 OK List completed.

it goes on like that in the log for every filter. What exactly is the BAD Error there, and is it something I can fix?
