I'm also an arch user and on the upgrade to kmail 2.1.1 had my settings migrated to the akonadi framework. This was somewhat problematic and I had the same issue sending via my SMTP settings.
I deleted my default setting and re-created it. It worked even though the settings hadn't changed.

Might be worth trying?
