Nick’s Review of Powermta Vs Postmark
The blog post titled “Better bounce categorization in Postmark” discusses the recent efforts made by Postmark to improve their bounce processing and categorization system. Bounces are an integral part of troubleshooting email delivery issues, and Postmark aims to provide accurate and detailed information to their customers regarding bounces. In the past, there have been instances where legitimate user addresses were mistakenly categorized as hard bounces, leading to the deactivation of those addresses.
To ensure the accuracy of their new bounce categorization system, Postmark conducted extensive testing. They compared the results of their new categorization method with the old system and made adjustments based on the discrepancies. They also tested different code libraries for bounce processing and analyzed thousands of different bounces to determine the most accurate categorization method.
Postmark utilizes multiple sources of input for their bounce processing. They use the ListNanny.Net library to parse bounces and extract valuable information from the raw message. They also take advantage of the bounce categories provided by PowerMTA, which categorize bounces based on factors such as policy-related issues and quota-issues. Additionally, regular expressions are used to detect specific diagnostic codes and content in the bounce messages.
To streamline their categorization process, Postmark created a JSON document that contains the rules for recategorizing bounces. This document is stored in CouchDB, and the bounce processing code reads these rules and applies them accordingly. This approach allows for easier addition or modification of recategorization rules without the need for redeployment.
The improvements made to the bounce categorization system have significant benefits for Postmark’s customers. The number of messages miscategorized as hard bounces has been reduced, resulting in fewer address deactivations. The new system allows Postmark to react quickly to identify and resolve inaccuracies in categorization. Ultimately, these enhancements mean that more messages can reach their intended recipients, and customers can focus more on their business rather than worrying about bounces.
Overall, Postmark’s efforts to improve their bounce categorization demonstrate their commitment to providing a reliable and efficient service to their customers. By continuously refining their systems and processes, they ensure high deliverability rates and a better user experience.
Tina’s Review of Powermta Vs Postmark
In a recent blog post, Postmark announced the introduction of their new Retention Add-on. This new feature aims to improve email deliverability and analytics for businesses using Postmark’s email services. The blog post goes on to explain the problem they were facing with their previous SMTP listeners feature and why they made the decision to move to Amazon EC2.
The previous implementation of the SMTP listeners feature relied on PowerMTA, a mail server product that listens on port 25 and accepts connections. When a new message is received, it would pass it to an external program through a pipe delivery mechanism. However, the solution was not ideal as it lacked scalability and automation capabilities.
To address these issues, Postmark decided to migrate their SMTP listeners to Amazon EC2. They chose to use Postfix as their mail server because of its ease of automation and compatibility with their requirements. By bundling Postfix with Dovecot, they were able to authenticate users against a SQL database, eliminating the need to write to config files and trigger configuration reloads.
One of the advantages of using Postfix is that it supports encrypted TLS connections, unlike their previous solution. This allows for better security and compatibility with mailers that support the STARTTLS SMTP extension. To further improve performance, Postmark decided to write their pipe delivery program in Lua instead of using .NET, as Lua is a lightweight and fast scripting language.
The migration process involved building tools to migrate existing SMTP credentials configurations to the new SQL-based login scheme. Postmark set up new instances of Postfix, tested them in isolation, and used Dynect to set up a DNS-based load balancer to gradually route traffic to the new instances. Eventually, they were able to switch all traffic to the new instances, ensuring a smooth transition.
Overall, the migration to Amazon EC2 and the adoption of Postfix and Lua have allowed Postmark to overcome their previous limitations and provide an improved email delivery experience for their customers. The Retention Add-on, along with other features of Postmark’s email services, helps businesses improve their email deliverability and gain valuable analytics insights.

Rick’s Review of Powermta Vs Postmark
In this blog post, we will be exploring the differences between PowerMTA and Postmark, two email delivery systems. To begin, let’s define some key terms used in the email delivery process.
Firstly, we have the MTA, which stands for Mail Transfer Agent. This software is responsible for transferring emails between the computers of the sender and the recipient using SMTP (Simple Mail Transfer Protocol) and the internet. The MTA receives the email from the MSA (Mail Submission Agent), which is a server program that checks the outgoing email from the MUA (Mail User Agent) and transfers it to the MTA. The MTA then determines how to transfer the email to the recipient by searching through name servers and the DNS (Domain Name Service) for their location. If the recipient is not on the same server, the MTA relays the message to the recipient’s mail server. It is important to note that there may be additional relays involved in the process.
In the comic “Journey to the Inbox,” MTAs are represented as local post offices, managed by a teller. They take outgoing messages and are able to look up the recipients’ whereabouts for delivery.
Next, we have the MDA (Mail Delivery Agent), which is another server program, this time on the recipient’s mail server. The MDA receives the email from the recipient’s MTA and delivers it to the recipient’s mailbox. In the comic, Calamity Jane plays the role of Outlook Oasis’ MDA.
The MUA, or Mail User Agent, is a computer application that allows users to receive and send emails. It can be a webmail email service like Gmail or a software application like Thunderbird. The MUA is what the human recipient user interacts with to read and respond to emails. In the comic, Jordan sends his email using Gmail as the sender’s MUA, and the email is delivered to Lucy’s Outlook.com mailbox as the recipient’s MUA.
Now let’s talk about email authentication methods. DKIM (DomainKeys Identified Mail) is an email security standard that uses public-key cryptography to sign email with a private key as it leaves the sending server. The recipient server then uses a public key published to a domain’s DNS to verify the source of the message and that the message’s body hasn’t changed during transit. In the comic, DKIM is represented by the sealed and signed envelope of Jordan’s message.
SPF (Sender Policy Framework) is another email authentication method that helps prevent spammers from sending emails on behalf of a domain. An organization can publish a list of authorized mail servers and IP addresses to DNS, and the recipient’s mail server can check the sending IP address to determine if the sender is authorized. In the comic, Jordan’s email is SPF authenticated using an SPF stamp.
IP reputation is an important factor in email delivery. An IP address develops a reputation based on its history and associations, and this can impact email delivery. Servers may reject or filter emails from IP addresses known to send spam or cause complaints. Good IP reputation improves the chances of email delivery. It is just one piece of the overall puzzle for email delivery, and there are many other factors involved.
Email authentication and IP reputation help reduce the chances of emails getting caught in spam filters and improve the chances of reaching the inbox. They provide verification of a message’s origin and help prove its legitimacy.
Spam filters are software implemented at various levels of email delivery to detect and prevent unwanted mail. They use content scanning and block/allow lists to determine if an email is spam. It is important to note that spam filters can be implemented at different stages of the email delivery process, from firewalls to the recipient’s mail server or even within the recipient’s own inbox. In the comic, Spam Filter Spot represents Outlook Oasis’ spam filter.
Spoofing is a technique used in spamming and phishing attacks. The spoofer tricks the email recipient into thinking the email was sent from a trusted person or organization. This can be done by sending from a domain without authentication methods, compromising a machine in the network, or using a lookalike domain. Authentication methods and spam filters help combat spoofing attempts. In the comic, Nosey McShnoz attempts to spoof Jordan’s email, but Spam Filter Spot is able to detect the spam and prevent the attack.
In conclusion, understanding the differences between PowerMTA and Postmark is essential for effective email delivery. Both systems play important roles in the email delivery process, ensuring that emails are sent and received securely and efficiently. By implementing proper authentication methods, monitoring IP reputation, and using spam filters, organizations can improve their chances of reaching the inbox. Stay vigilant against spoofing attempts and take advantage of email authentication to protect your email communication.
