Original bug dates back more than a year. Scanning distro user lists finds many other people having the same issue. Expect more people having issue now that gmail offers imap support.  

+++ This bug was initially created as a clone of Bug #368417 +++

Please describe the problem:
Connecting to an Exchange 5.5 server using IMAP mode, filters on the inbox are not automatically run. "Apply filters to new messages in INBOX on this server" is checked. Incoming mail, once manually selected, and 'ctrl-y' is hit, are filtered as expected and, occasionally, filters -will- automatically run, usually just after a manual filter or an expunge, but never if there is already mail that is not filtered in the inbox.

Steps to reproduce:
1. Wait.
2. New mail fails to be filtered.
3. Select mail and apply filters works as expected.


Actual results:
New mail is not filtered.

Expected results:
New mail should automatically be filtered since "Apply filters to new messages in INBOX on this server" is checked.

Does this happen every time?
This happens 99.9% of the time. New mail occasionally filters just after a manual filter or an expunge.

Other information:
I have tried completely deleting and recreating the account in Evolution, but this has had no effect.
