#10 Spampal+Stunnel+Opera: message fetching hungs

[Mahlerite]

I use Win2KProSP4, the Opera integrated email client (version 9.25, the last stable build) with spampal 1.73g transparent proxy and stunnel. When more than one message is on server and Opera tries to download them, it often stops with the umbrella spinning. It does not hang, it simply keeps on spinning and spinning. I have to terminate the connection (via spampal), disable filtering, hit the "receive" button and re-enable filtering. I can do that very quickly so that the messages are actually filtered, so it looks like the very first stage of filtering is the culprit.
If somebody wants to try reproding this bug I suggest to use the same configuration as mine. You may not get the problem immediately but keep on using it 1-2 days, you should get stuck like me.
