This discussion has been in the context of _storing_ user email.  The assumption
is that an OP is smart/talented enough to get his spam filters/appliances
killing 99% before it reaches intermediate storage or mailboxes.  Thus, in the
context of this discussion, the average size of a spam message is irrelevant,
because we're talking about what goes into the mail store.

If you're storing significantly more than 1% of spam you need to get that under
control before doing any kind of meaningful analysis of mail storage needs.
