I see I’m a year late to this thread, but I Googled it up today because I was searching if any other SpamSieve users had this issue like I do. Sure enough, the person who started this thread has the same problem I do. Then again, I think most SpamSieve users do – they just endure it.
I’ve endured this slowness for a long time, even when I was using Entourage. It was slow with Entourage and after updating to Outlook 2011, the speed did not increase at all. Yes, I followed your Outlook instructions precisely, and I don’t have any Outlook rules that call the “SpamSieve - Move if Spam\cmM” script. I know my Outlook setup with SpamSieve is 100% correct. And yet, whenever I check email, if there are a lot of new incoming messages, Outlook always locks-up until SpamSieve is finished. When I say “lock-up” I mean it too. I cannot do anything at all in Outlook until SpamSieve is finished. I know it is SpamSieve because this lockup only occurs when I see the little white dot flashing on the SpamSieve icon in the Dock.
I’ve somewhat learned to live with it, which is why after all this time I’ve never reported it here. I always thought that was the trade-off for having a reduced number of SPAM messages! But honestly, there is a point when it can be frustrating. And I did wish it could be multi-threaded (if it isn’t already) so as to speed up whatever it is that SpamSieve does during these slow-downs/lock-ups.
I still love SpamSieve and would never do without it. It’s just slow when it filters through incoming emails, whether that be POP or IMAP.
