[Dovecot] Problems with BEFORE searches.

Ok, I am trying to modify some code given to me by the author of the dspam plugin for dovecot (sorry the name eludes me). I am modifying it to handle UNSEEN differently than SEEN.

Below is the python code. I am not a python programmer, but I get the basic idea.

ok, uids = conn.search(None, 'BEFORE', unreadsentbefore, 'SEEN')

"11-May-2007 06:18:29 -0600" is the value of unreadsentbefore.

However, this doesn't match any emails even though they are all dated as 5/10 and they have all been read for several hours (the time was the current to figure out why it isn't working).

Is there a problem with BEFORE and SEEN together? Is there a BEFORE bug in the system? Some of the messages are -500 and others, I am not sure.

Thanks, Trever Adams
