Configuring for Reliable Email Sending

Are there any good articles about how to configure your XenForo host to send emails reliably (so they are not treated as SPAM)?

Ideally, I'd like the emails that go our for verification of new registrations to come from - but that is a Google Apps account. Another alternative we've been looking at is using SendGrid. But, I'm not sure what is the best way to hook up the Zend Framework mail transport that XenForo uses with either Google Apps or with SendGrid.

We are running XenForo on Ubuntu 13.04 on an Amazon EC2 instance.
Cause I'm not sure how to make it work with XenForo. That's why I'm posting here. To see if anybody has pointers about how to configure XenForo with SendGrid, or SES, or whatever. Just need it to be reliable and not sending emails to SPAM.
Thanks - I thought it would be harder! So, I just configured SMTP to work with SendGrid. We've had some deliverability problems with SES and like SendGrid better.

I recently started using and I'm quite happy with them. Pricing is like double of Amazon SES, but Mandrill is a ready-to-use service, plus you have nice charts to see how your sending emails are going.
Thanks. We had problems with SES blacklisting our customers. Not us, but whenever an email would bounce, SES would not send to that email address any longer. Some perfectly fine email addresses would occasionally bounce and end up on this list. There was not obvious way to see the list or get alerted to when this happened. That was about a year ago. Might be different now.
