This plugin is the most lightweight and does it's job well. You also have the test mail functionality that gives you output to fix any problems there might be. Download the others here on and you will see some are megabytes, the smaller a plugin the less of a performance footprint it will have on your site. Go for this one.

Straightforward, easy to configure, and unobtrusive (doesn't take up its own menu entry in WP Admin). Hidden bonus: probably the only mailer plugin that gives you visibility into the full SMTP client/server session. Allows for serious debugging!

SMTP Mailer is a simple, but reliable plugin for sending emails via SMTP. It doesn't feature any special APIs, which keeps it small and quick, but it works, and the author keeps up to date with issues and environmental changes. I use it for Amazon SES on several sites and it works great.
