Duplicate of bug 139561, which is the result of temporary work performed for
beta in bug 125607.

Note that this size and protocol dependent.  It also reacts differently to
inline vs non-inline attachments.

Also note:  Current behavior is almost identical to that in NS4.79.  The
proposed 'final' fix will allow verification on demand, in addition to the
questionable signature icon/message.
