Moving the API to Amazon EC2

While working on Postmark and dealing with everyday small improvements we noticed we needed to take greater steps to keep it up with the demand.

It keeps us in shape; we have to keep up with new technologies so we can provide best service for our customers. We recently introduced several changes under the hood of Postmark – this article is on changes affecting the Postmark API.

While PowerMTA really shines when quickly sending gazillion of emails at the same time, it is not very automatable. We had to edit config files and launch external processes to signal a configuration change and make the sender load the new settings.
