Hi!
 
I recently installed SpamAssassin 3.0.0. What I'm trying to do, is having it scan a mixed mailbox, split the mail into two seperate mailboxes (spam.mbox and ham.mbox) and then analyze how successful it was.
I do this with:
formail -s procmail -m sa.check < mixed.mbox
 
where sa.check contains:
:0fw
| spamassassin
 
:0:
* ^X-Spam-Status:(.*\<)?Yes
spam.mbox
 
:0:
ham.mbox
 
So far, everything works OK.
Then I run sa-learn on my hand-scanned mailboxes Spam and Ham (see stats below)(it says it learned from all the messagess I fed to it), and rerun SpamAssassin same way I did the first time.
 
Here's where my problem lies:
Actual stats:
Mixed: 1812
Spam: 1150
Ham: 662
 
Stats after 2nd run:
Spam.mbox: 956
Ham.mbox: 855
... the thing is, the stats I get after the second run are the same as they were after the first!!! But they very much shouldn't be, as Mixed mailbox is actually Spam and Ham mailboxes put together (and SA learned from them before it did the 2nd run!).
Just like it didn't learn at all (but it said it did).
 
Before I tried this on SA 3.0.0 I did it on SA 2.64 - worked fine.
The results after the 1st run were not as good as after SA 3.0.0.'s 1st run, but after i sa-learn-ed it, it got all the mail correct in the 2nd run.
 
What bothers me is what am I doing wrong? Is there some catch with SA 3.0.0? Something I've overlooked?
 
Please help!
 
Thanks,
Insems
