While it's true that python's threads are limited to using a single CPU at a time, it sounds like your bottleneck is network IO, not CPU power. I imagine that your one CPU is doing a lot of idling, thumb-twiddling, etc., while waiting for the remote email server to respond. In such a scenario, python's threads will work fine to speed your application. On the other hand, adding CPUs to an IO-bound application isn't likely to speed it up at all.
