fix from entries being shown even with a from filter

fix from entries being shown even with a from filter

When a 'from' and 'to' filter were set, we used a 'from || to' test to
see if we should print it or not. This patch changes this to a 'from &&
to' test. This gets rid of entries from unrelated senders ('from') when
a 'from filter did not match but the 'to' filter matched.
