I wanted to share a service I discovered that appears to be very good for Email relaying. This is what you need to send emails (like notification emails) from a Connector. Typically, we've recommended Gmail, or Yahoo, but sometimes this can be an issue due to their on-going changes to battle people using their servers to relay spam emails.
The service I found is Easy SMTP. http://www.easy-smtp.com
You can get 10,000 email relayed per-month for free. So for most of you, that's a great price!
Check it out... there are others services and I'm not sure if Easy SMTP works outside of North America.
P.S. This also works well for Switch born emails.
Enjoy!
