Ask HN: Replacement for Rackspace SMTP Hosting?

Just got email, Rackspace increases monthly minimum to $12 (was $10) for basic SMTP hosting.

I barely use it, but I like having a solid, independent, third-party, basic SMTP host around for when it is useful.

Name me a suggestion. I know 20% or $2 increase isn't much, but I don't want to pay that much for something I barely use, but I need something.

This unwanted fee increase has me jumping ship, not sure where to yet.

Thanks.
