Nope - That was one of the first things I thought of.  Nothing like that
today, plus the machine wasn't particularly busy at that time. Its always
possible that the syslog was swamped and messages were lost, but I doubt
it, it wasn't that busy.

Using Pine, I checked the message ID and scanned the syslog (which
includes both spamd and sendmail entries) and located the message being
handed off to procmail. It wasn't even slightly busy at that time.

I also considred that procmail might have screwed up and bypassed spamd,
but I don't see anything in the message that hinted at that.

Want to see the spam in question? I could send it as an attachment.
