Marking worksforme since a lot of spam filter code has changed since TB 0.3.
Reporter, please reopen if you still see this.

Thunderbird version 1.5 (20051201); Mac OS 10.3.9

I have seen this behaviour all through Thunderbird 1.0.x and have now reproduced it in 1.5rc2.

Steps to Reproduce:
1. For a given email account on a server which supports both POP and IMAP, set up both an IMAP and a POP account in Thunderbird.

Actual Results:
On occasion a message will be marked as spam in one of Thunderbird's accounts but not in the other.

Expected Results:
Identical message downloaded from the server should be filtered consistently in Thunderbird's POP and IMAP accounts.

Additional Notes:
IMAP and POP accounts are set for SSL access with no secure authentication. Server address in TB is different, but the two addresses resolve to the same IP and server. The training.dat file was reset on upgrade to 15.rc2. Under previous versions of TB, this behaviour was observed on two different servers.

See Bug 284308 Comment #6 for some statistics which show the spam filter performing inconsistently on identical messages.

I believe that this bug is present in version 1.5 (20051201). Could someone with the appropriate privs please reopen it?
