I don't think that second spike is odd. That's the majority of your ham.
Since the data-set includes both spam and ham combined, there are two
spikes to be expected. A single bell curve would mean too many messages
in the gray area, no clear distinction between ham and spam, and
consequently lots of false positives and negatives.
