MailerQ version 5.2 has been released!

We are happy to announce the release of MailerQ version 5.2! MailerQ 5.2 includes two highly requested and exciting new features:

Response patterns

Bounced emails can cause problems when they are not handled appropriately. For example, when you continuously send emails to invalid addresses this can lead to your IP address getting blocked by ISPs. With this in mind, we have enabled response patterns. You can now define follow-up actions based on the bounce response from the receiving server. Based on the response, you can choose a suitable follow-up action that will be applied to all emails that have received a similar response.

Bounce responses can also be classified. For instance, you can choose to classify responses [550 Invalid recipient],[501 Bad address] and [500 No such user] under class: Invalid_recipient and set a follow-up action for all responses under this class.

The response patterns feature helps to show the ISPs that you review the responses from the mailbox provider. It shows that you care about your sender reputation. This will ensure that you maximize your email deliverability and overall sender reputation.

Flexible log formats

Users can now decide in what format they want to store their log files using SMART-TPL. Are you still on a different Mail Transfer Agent than MailerQ and are looking to make the switch? The introduction of this new feature enables you to set-up MailerQ as a drop-in replacement of your traditional MTA without having to make huge changes to your current system set-up. This saves time, allows for a seamless transition to MailerQ and provides more flexibility in your infrastructure.

Aside from the new features, MailerQ 5.2 also includes bug fixes and other improvements:

Bug Fixes:

Other improvements:
