Of all the Amazon Web Services I use, the Simple Email Service would have to be the service I use the most. ColdFusion allows me to easily create a component that sends emails pragmatically but, however, it would be much nicer to use the CFMAIL tag and be done with it. As it turns out, Amazon SES allows you to send a raw email so you can run PostFix to relay the message through Amazon SES using a perl script.
I found a good tutorial on getting this configured here. I did have an issue getting perl to find the SES.pm file, but this post details how to work around that issue. The great thing about handling it this way is other applications on the server can send messages through the gateway, not just ColdFusion applications.
