No worries.  We are all victims of missing things, especially in a stressful
situation.

That seems like a reasonable assumption in that specific case.  However, it
may not be a good assumption with the large audience that SA serves.  Some
people get more spam than ham, others get more ham than spam, and yet others
get roughly even amounts.  It sounds like your experience is more on the
extreme upper-end of spam/ham ratio.  I would think that at either end of
the spectrum though, the To: field is not a good indicator of either spam or
ham regardless of the numbers.
