After doing the various tuning steps yesterday, our server is running
much better right now. Currently, our max spamd child processes value
is set to 60.
I have a message that came through completely unfiltered a short while
ago. It was a drug spam with one of the "remove ... from the link" URLs.
All of our servers are running NTP and the clocks appear to be synced so
log correlation should be accurate.
Here are the headers of the message:

Here are the logs from our external Qmail server. The first entry was
the message being received from the Internet and being delivered locally
due to virtual domains and alias expansion, which is where the call to
SpamAssassin occurs. The second entry is the resulting email with a
modified 'to' address being delivered inwards to our AV server. spamd
is using the default timeout of 600 seconds, so if there had been some
problem connecting to the spamd server, it should have waited and
retried, yes?

The 15809 child was finished at this time and it looks like the parent
process was doing some housecleaning work regarding the child process.
But this shouldn't affect other incoming connections, right?
Any ideas why this message gave up on SA so fast and went through unscanned?
Thanks,
David Goldsmith
