User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3
Build Identifier: Version 2.0.0.0 (20070326)

i have different filters moving the incoming mail to different imap-folders:
- subject beginning with "***SPAM" to Spam-Folder
- subject beginning with "OTS" to OTS-Folder

nonetheless, thunderbird moves most of the mails correctly, but from time to time there's a Spam-Mail in the OTS-Folder or the other way round. that's critical to me, 'cause i have to trust my email client.

i experienced this problem on different computers (all windows) and different imap-servers (courier, zimbra)

this problem exists since versions, i wonder noone reported this bug yet

Reproducible: Sometimes

Steps to Reproduce:
1. use IMAP
2. add two filters, reacting on different things
3. get few thousand mails and wait
Actual Results:  
described in the details, mails are filtered wrong

Expected Results:  
it should filter correctly

Philipp: Could you please provide more information for better reproducibility?

For example, do you have a filter log of what happens when these messages slip through?

Our old mail server had serious hardware problems which caused several strange problems. Since january our new server is in use and I couldn't notice any further wrong behaviour with our mails or Thunderbird. So this is no Thunderbird issue. Resolved as invalid.
