Postfix SMTP AUTH w/TLS

The sysadmins at TnR Global, LLC enable email to be successfully delivered from EC2 instances, instead of being caught by Spamhaus and others.

One of the widely discussed issues with Amazon EC2 instances is the inability to reliably send email from the instances. In all too many cases, email from EC2  instances is automatically categorized as spam by the various relay databases, and by many ISP’s and carriers. There are several solutions, with the most common being a smarthost setup using either an external smarthost smtp service, such as http://authsmtp.com, or using an existing smtp server within our infrastructure.

Will Amazon AWS save me money?

One of this first questions we asked when deciding to sue Amazon’s AWS services was: Will we save money?

At first, your EC2 servers may be simply architected, perhaps small instances. Once a more serious commitment is made for a more robust architecture at Amazon, there will be additional costs introduced. For example, a small instance, running a 2 disk 100GB EBS volume w/RAID0 plus monitoring and a static IP, and the cost goes from the current ~$68 monthly per system to ~$88 monthly per system. Bump the instances to large instances (likely needed for any server running mysql, or any other equally intensive application) and that cost goes to ~$265 per instance. Add in the costs of the additional services like bandwidth, Static IP, Cloudwatch etc and the costs can quickly escalate. Of course, upfront payments for Reserved Instances can drastically reduce the costs further.

However, the savings in development and deployment costs I think far outweighs a narrower gap in the savings between physical and AWS servers, and the real MRC on the AWS servers will likely be lower for a given amount of computing resources.

So- can you save money? Yes. In some cases, it will be a direct apples to oranges savings of hard dollars. In other cases, the agility gained will provide the greatest savings. In most cases- a combination of both will drive your cost savings.
