I've been using POPfile 1.0.1 with IMAP (started with runpopfile.exe on Windows XP). It has been working for 3 months without any problems. Last week I had to change my IMAP server and since then POPfile hasn't classified any emails but also hasn't complained.

I can go into Configuration and tell POPFile to query the server for folders which it happily does, updating the list of folders. If I give a bogus password it complains so that suggests that it connects happily.

The log within the POPFile UI shows:

2008/8/28 16:12:08 17460: ---------------

Note that my update interval is 280 seconds.

Are there any debug flags I can set to find out why POPFile is no longer classifying the emails?

Thanks!
