Summary: Spambayes slow with XP SP2?

Initial Comment:
I'm not sure if my perception is correct on this but it 
seems like spambayes may be slower after SP2 is 
installed.  I had been noticing that it was taking a long 
time for spambayes to move recently received spam into 
the Junk E-mail folder.  I had installed spambayes and 
SP2 on another computer and the user of that computer 
also noticed that it seemed slower.  It still works and I 
don't have any hard evidence that the slowness was 
caused by SP2.  We are using spambayes in conjunction 
with Outlook.

Note: I also submitted 799201.  That submission is 
bogus.  It was my fault.  I didn't understand how 
spambayes worked.  799201 can be ignored.

Thanks for your work on Spambayes - It's awesome!

OK, more on this. The problem is the Windows XP/SP2 firewall. 
Assuming that everyone who's meeting this is running against 
Microsoft Exchange, then the problem appears to be that the 
firewall is blocking (dropping) connections sent from Exchange 
to Outlook via a UDP port. I'm guessing that somehow 
Exchange signals to Outlook that it needs to refresh/redisplay 
via that port.

If you enable the SP2 firewall logging and look at the log file, 
you'll see the dropped connections from your Exchange server 
to your machine on a UDP port > 1024. Unfortunately, the 
port that is used is dynamically assigned by default. I believe 
if you search MS Knowledge Base you'll find some registry 
settings to force the connection to a specific port.

So unless I'm missing something (quite possible) the only 
options are to force the connection to a specific port and 
define that port as an exception within the SP2 firewall or to 
add Outlook itself as an exception to the firewall. Certainly 
the latter restores the timely update of Outlook once 
Spambayes has done it bit. You may wish to consider the 
security implications of adding (the whole of) Outlook as an 
exception to the firewall... 

Maybe there's a way of SpamBayes itself forcing a refresh?

Just following up on my earlier comment - and to agree with 
wormeater...

It would appear that Spambayes is performing as normal BUT 
not it/Outlook is not updating the display. If I get an obvious 
spam message in, wait a few seconds and then double-click 
to open it, it says the item can't be found - because it has in 
fact been moved.

BTW I did try the obvious thing of reinstalling SpamBayes 
after having installed SP2 but that didn't make it better.

I've been having the same problems since installing SP2
about a week ago.  It seems to be classifying the mail but
for some reason it's not updating.  I say this because you
can always speed up the process by opening messages or
switching to another mailbox.  You may have many spam emails
in the Inbox, but as soon as you view any other mailbox, and
go back, they will all disappear.  The same thing happens if
you open an email in the Inbox.

No, it's not your perception... I can confirm this. Everything 
was fine before SP2 - Spambayes would display the %age 
Spam likelihood after less than five seconds of emails 
appearing in my Inbox, but now it's a good minute before the 
%age appears.
