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. The volume of emails delivered by Postmark is growing from week to week and we’re thankful for it. 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.

We’re Not Dead Yet

It’s been an interesting first month for me at Wildbit — last week, we heard that Amazon had released a product called “Elastic Beanstalk” (for those who don’t know, one of our other products is called Beanstalk). This morning, we woke up to find that they’d announced a competitor to Postmark.

Moving SMTP Listeners to Amazon EC2

Ever since we launched our SMTP listeners feature, something has been bothering me. The feature worked, but it wasn’t exactly how I wanted it to be. Here is how we had it implemented:

  • The mail server (we use Port 25’s fine PowerMTA product) listens on port 25 and accepts connections. Whenever it receives a new message, it passes it to an external program. That is called a pipe delivery mechanism since the external program is a console tool that gets launched by the mail server and the message is piped to its standard input stream.
  • We built a sophisticated management solution that modified the PowerMTA configuration whenever a customer registered a server for SMTP access. 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.

Oddities in Gmail delivery - Adaptive Filters

I don’t know about you, but I’ve been pretty spoiled with a great email client (Gmail) and how it handles the spam that comes through my mailbox. It’s rare it ever gets to my Inbox, and I monitor my Spam folder periodically to make sure no legitimate mail gets there, and it rarely does. I would say this is magic, but, I know better. Gmail takes very good care of its users, like, impeccable care. But, there’s always an expense, and in this case it’s at the expense of the sender.

What we've been up to...

It’s been way too long since we published anything on the blog. This, of course, does not mean we’ve been on vacation. We’ve had some incredible growth in the last few months which has put a lot of our focus inward on our infrastructure and support to help the new (and existing) customers. I wanted to give you a quick update on what we’ve been doing behind the scenes.
