I've seen that happen on SA servers/mailserver running SA, that are
"under-powered" (for lack of a better term), or over-processed.
Either processor or memory utization is being drained by either the SA
processes or the MTA, or a combination of the two (or other services running
on the same box), causing SA to not scan/score/stamp depending on the load
of incoming messages at any given time.

Hi, I am noticing a disturbing trend within the past month. I'm noticing
mails coming thru without any of the normal Spam headers, such as:
X-Spam-Checker-Version:
X-Spam-Level:
X-Spam-Status:

These mails inevitably are *never* caught as spam. I can't even check what
score they were given, since none of the usual headers are there. From
looking at the message delivery paths, I can see the mail *should* have been
processed by SA, as it's passed onto exim with -P spam-scanned - this is the
standard Debian setup with a SA transport using spamc and spamd. My best
guess, is maybe 5-10% are missing headers?! rough guess.

Has anyone seen similar behavior? I hope someone can provide insight as to
what may be wrong? Thanks!

Jay

Hello,

I would get emails scored with (?/?) that would pass through.  I just
configured my system with qmail-scanner to block misaddressed emails at the
SMTP conversation level and the problem went away.
